From the notebooks 3 – TSP 2008 galaxies

Some galaxy sketches to brighten up your (and my) day – and mine is in serious need of a brighten up! These were made at the 2008 TSP, while observing with Larry Mitchell’s 36″.

NGC 5907, Draco
Spectacular, cutting right across the field of view in the 36″ at 232x. Prominent dark lane and a bright, elongated nucleus. Very thin, indeed. I am fond of edge on galaxies and this is one of the best.

Hickson 44, Leo.
A nice group of which NGC 3190 is the brightest member. 3190 (below centre) has a prominent dark lane. NGC 3187 (to the left of 3190) is faint and evenly bright. NGC 3185 (top) has a slight brightening towards the centre. NGC 3193 (bottom right) is round with a dense core and a fuzzy halo.
36″ at 232x.

NGC 4206 and 4216, Virgo
A lovely view. 4216, the large galaxy at right is very large, very bright and elongated. It also has a very bright compact core.
NGC 4206 is much smaller and fainter and does not have a bright core.
36″ at 232x.

M52 and NGC 5195, Arp 85, Canes Venatici
This is one of the best views I’ve ever had of this pair. You line up the huge dob, go up the ladder and this dinner plate, with the little saucer NGC 5195 next to it, is in the eyepiece.
It was hard to draw, as I was balancing near the very top of the ladder.
The arms are not uniformly circular as they appear in smaller apertures. They are bent, probably due to the influence of  5195 nearby distorting them. There are bright HII regions in the arms.
The bridge of material connecting them is easily seen and quite bright in the 36″ at 232x.
5195 is oval, distorted. the side nearest M51 is brighter than the side away from it. Fantastic.

‘From the notebooks’ does sound a little pretentious (I was going to say ‘poncey’!) but it’s quite a good title – and this stuff IS from the notebooks! – and posting old sketches is a good way of keeping the blog active while I scratch about for something interesting to post. It’s gone dead observing-wise here, due to the most appalling weather (August has been a total wash-out this year, with torrential rain, flooding and gales. I feel sorry for anyone on holiday here, especially if they’re camping) and the last few nights the Moon’s been in the way. The beginning of the month was okay for observing, with one okayish night, one good night, the Perseid peak, the Milky Way sketching session and that absolutely sensational night we had.
Anyway, some more ‘From the notebook’ type posts will appear over time, depending on what else I can talk about. It depends on how much observing I get in. I’m hoping the weather will improve during September.

Off topic, but still relevant (which I’ll come to in a minute) is my work situation. I’m currently doing a seasonal driving job delivering tourist guides to hotels, attractions, ferries and train stations, etc, which I like very much. It’s part time which suits me nicely as I can start what time I like – very handy after late observing sessions and all-night runs! However, with the tourist season winding down soon and just another couple of weeks to go of the main season, my hours will probably get reduced.
I can’t find anything else at the moment as the employment situation in the UK as a whole, not just where I live, is appalling. I’m getting interviews but then nothing comes of them, usually it’s because there’s always some git with more experience than me (although I am sure it comes down to pulling names out of a hat). Even the temping agencies have nothing – indeed the manager of one described the situation to me as ‘absolute crap’, and when even the agencies use words like ‘crap’ you know it’s bad indeed. The fact that a very real threat of a ‘double-dip’ recession is hanging over the country (although I do get the feeling the Bank of England and the Treasury are talking us into this, aided and abetted by the media) does not help the situation any.
Despite this, I am still planning to get a 20″ dob (I am one of these people who has to have something to aim for – I do NOT believe in just existing, because that’s just depressing and pointless), firstly buying that mirror-less scope I’ve mentioned in previous posts, as I already have most of the money for that. The mirror might take longer to acquire than I previously hoped, though, depending on what happens on the work front.

I am pleased to say the observing shed has held up in the recent bad weather. Some rain got blown in through the vents, as it has been pretty much torrential and blown horizontally for the past few days, but otherwise – touch wood – it seems more or less ok. I did seal up non-vent suspect points with duct tape and also fixed the roof down better, just in case as I don’t trust their flimsy method of attaching the roof. I also stuffed an old t-shirt into the vent where the rain was being blown in, I’ll remove this when the weather improves. Let’s hope it continues to be dry in there. The mirror also looks as if it’s remained condensation-free, so the silica gel cat litter seems to be doing the trick.

New Facebook page

**Shameless Plug**

Being bored sat at home with my bad ankle, I decided to start a Facebook page devoted to Astronomical Sketching. If you’re a member of Facebook and are interested in sketching – it doesn’t matter whether you’re interested on the deep sky, moon, sun or planets, all are welcome – then please feel free to join.

I have a long way to go!

I have just been visiting some of the links on my website. One of these is of the homepage of famed visual deep sky observer Barbara Wilson of Houston TX. On there, she has a page about her astronomy exploits and, on it, she tells us how many things she has seen. As you’d expect, an observer like Barbara has seen a lot. In her own words she has:

“…observed thousands of galaxies, hundreds of  galaxy clusters, completed the Herschel 400, the Messier 110, I have observed all but 25 of the Arp Galaxies, all except for 10 of the Milky Way globular clusters, hundreds of open clusters, asteroids, dozens of comets, several great meteor showers, including the Leonids of 1998, and 2001, planetary nebulae, diffuse nebulae, reflection nebulae, asteroid occultations, lunar grazes, (I once got 36 events on a graze of Beta Tauri), solar eclipses (5 total eclipses), dozens of lunar eclipses, iridium flares, earth x crossing asteroids, supernovae, and never have seen anything in the sky that could not be explained in one way or another.“
I hope that by the time I get to Barbara’s age I will have a comparable record, but I have a long way to go (I hasten to add that’s in terms of things seen!)! To date, I have seen a lot of things out there (and, like Barbara, never anything that cannot be totally explained) but not the sheer amount of objects that Barbara has seen. What I’ve seen probably numbers in the high hundreds, not quite the thousands, not that I’ve actually properly counted.

Another visual observer who has seen a tremendous amount is Steve Gottlieb of California, who has notes on the entire NGC catalogue. He is part of the NGC/IC project, which aims to correct discrepancies and errors in the NGC/IC catalogue and, as part of this project Steve (and others) has reobserved the entire NGC/IC and done an excellent job in clearing up the errors. Steve’s NGC notes can be found here, alongside those of Jeffrey Corder and others.

These are but two of those who have seen, if not it all, certainly most of it. These people have been observing a lot longer than I have, but it shows what dedication, a lot of clear nights and a lot of skill can bring. My current observing projects – the Herschel 400, Herschel II, then the rest of the Herschels, making the Herschel 2500, plus Arp galaxies and galaxy groups and clusters – will go a long way towards my goal of achieving this sort of accomplishment for myself. This is especially the case as I have done a lot of observing since 1993 but none of it systematic projects. Having a systematic project helps a lot in keeping your observing structured and thus, keeping track of things.
A larger scope will also help a lot, as will a few more trips south of the Equator.

Now, you might ask, what am I doing posting on here in the evening, when I could be observing and catching up with the likes of Barbara and Steve, et al? I wish I was out there, but unfortunately the Moon, clouds and a wrecked ankle after an accident in the kitchen earlier this week (I slipped on a wet patch on the kitchen floor and have torn the ligaments in my right ankle) all say ‘no’.
I can’t wait to get back into things, once my ankle’s better, the Moon’s gone and – hopefully – the clouds have cleared.

Milky Way sketch

After yesterday’s rather lengthy rant it’s back to the observing!
Last night, it unexpectedly cleared so it was time for some observing. However, the forecast called for it to cloud up so I decided on a short session and to do something a little different.
Back in 2006 I decided that doing a sketch of the Milky Way would be a cool thing to do. At that time, I’d torn a muscle in my back and couldn’t carry my scope in and out, so I began a naked eye sketch of our galaxy through Cygnus and down towards Sagittarius. I never finished that sketch as the weather closed in for a few weeks and my back got better. I dug out that sketch recently and decided to have another go at it. I decided that I’d start again from scratch as the 2006 sketch wasn’t that great.

Last night’s sketch was done while lying prone in a reclining garden lounger and it wasn’t easy, with the sketch book held upright on my chest it made for an awkward process. I decided to just do the part of the Milky Way that runs through Cygnus and slightly south. I included Cygnus, Lyra and Aquila in the sketch but left out the other constellations in that area. I also only added the brightest stars – I’d have been there a week if I’d tried to put all of them in, as it was mag 6.5+ at the zenith!
Unfortunately, by the time I’d got as far as adding the Milky Way glow the sky started to deteriorate with mist moving in.
For the sketch, I used an A4 (11.75×8.5 inches/297x210mm) sketchbook with heavy cartridge paper (my usual book for sketches), a 2B pencil for the stars, a 4B for the Milky Way and a chamois leather for the smudging. I’d never previously used a chamois leather before as it never even occurred to me, but it is ten times more effective for smudging nebulosity than a blending stump (tortillon) or finger tip is; how I’d heard about using a chamois was via Jeremy Perez’s excellent Astronomy Now series Drawn To The Universe. I bought mine from Halfords (for people outside the UK, Halfords are a retail chain who sell car and bike accessories), for around £3.99. It smells disgusting but works a treat!

The sketch isn’t totally complete, I really should have added more stars and the surrounding constellations, such as Delphinus, Lacerta and Sagitta, etc, but I daresay I will repeat this at another time, when conditions are better and I have more time.

Here we go again

Year after year the debate about changing to permanent British Summer Time (an hour ahead of Greenwich Mean Time – incidentally the same as Universal Time) crops up as soon as autumn appears on the horizon. This time the Prime Minister, David Cameron, has joined in wanting the country to adopt BST year round, according to the Torygraph. Not only that, he wants DOUBLE BST which effectively means the clocks going forward by 2 hours in summer and then back 1 hour in winter and doing away completely with Greenwich Mean Time.
It’s already hard to practise this hobby here anyway due to our climate and the sheer amount of light pollution – although here on the Isle of Wight, we’re more fortunate than a lot of people as we have a higher incidence of clear nights and less light pollution than the adjacent mainland –  and dicking about putting the clocks forward every March just adds insult to injury as summer observing becomes almost impossible, particularly for people having to get up for work in the morning. Putting the clocks forward two hours would mean that any summer observing here would be completely impossible, certainly during the week.

In my opinion, putting the clocks forward in March and leaving them forward until October is a complete waste of time (pun intended) because the evenings are light from May until late August in any case, as are the mornings. When you get to winter, when the time has reverted to GMT, both mornings and evenings are dark. So what’s the point of changing? It’s pointless and ridiculous and only panders to the general public who seem to think that altering the clocks alters the earth’s orbital tilt and rotation!

The excuses for changing the clocks is nothing to do with crops and farmers any more, as was once the case. No the new excuses vary from road accidents during dark evenings to tourism.

The Royal Society for the Prevention of Accidents backs a change, saying that it’ll prevent road accidents on dark evenings. So what about dark mornings then? There are plenty of RTAs on dark mornings, plus mornings have the added ‘bonus’ of people being sleepy and not ‘with it’.
So that’s nonsense for a start and what about the main cause of accidents? It’s not the dark that causes accidents, it’s moronic and careless driving that causes accidents. Accidents are caused by excessive speed in inappropriate conditions and on badly-maintained roads, they’re caused by tailgating, overtaking into oncoming traffic or on corners and the brows of hills, cutting people up and other forms of bad driving. They are not caused by dark and if dark is a factor it’s because someone is not driving with due care and attention.
Not only that, I am not a morning person and, long observing session or not, I find it difficult getting out of bed in winter anyway because it’s so dark and I am not sociable at all until at least 10am. This change would make that a lot worse.

Environmentalists say we’ll use less electricity during the evenings, which conveniently forgets that we’ll end up using more electricity in the dark mornings instead. When you have to get up at 0600 to be at work by 0830 and it won’t get light until 0900 then you are still going to use a good deal of electricity in the mornings, so I don’t see the environmental angle at all.

Another reason is tourism. Who decides to go somewhere based on the time zone anyway? And, considering the country is even more damp and cold in winter than it is in summer (when it’s merely often damp and a bit chilly), tourism wouldn’t play a part anyway – why come to rainy old Britain in autumn and winter when you could go to the Canary Islands or somewhere else far pleasanter and warmer?

And then there’s the completely daft and spurious argument that ‘we’ll get more daylight’. Er, NO WE WON’T! How many times does it have to be spelled out to some people that we do NOT physically get more daylight?! Some members of the public seem to have difficulty grasping the idea that BST does not mean we get extra daylight, that the hours of day and night remain the same and that all BST does is just move the clocks an hour forward. Daylight just starts and finishes later, there isn’t actually more of it.
If people want more daylight, then go to lower latitudes in winter.

I hope that this stupid and halfwitted idea does not become a reality. With a bit of luck the Scots will have a lot to say about it because Cameron has insisted that the entire UK and not just parts of it would have to be included in this hare-brained idea and Scotland is very dark in winter. I know there is a lot of opposition to this in Scotland, where permanent BST would be a big problem for them with no daylight until at least 1000 in winter.
BST in winter would not, admittedly, be a big obstacle for observing as I can usually be observing by 5pm on a clear winter evening during the weekend. If it’s a week night, by the time I’ve got home and the evening meal is done and finished with, it’s usually 6.30 by the time I can get outside and still have a long observing session until 11pm or midnight. But that’s not the point because I oppose year-round BST on sheer bloody principle! And I especially oppose BST +1 because there is actually no sound reason whatsoever to change the clocks from the present system.


Oh and to add to my good mood, forecasters have predicted that the weather’s likely to be rubbish until November. Great. I just hope it’s the usual forecasters’ trick of making a long-term prediction only for it to be totally wide of the mark, like they have for the past few years. Knowing my luck it will be right for once.


Perseids, 12th-13th August

After practically hopping with frustration during the earlier part of the evening, I was pleased to see the skies finally (partially) clear around midnight, so I pulled out the sun lounger, got a blanket to keep my legs warm (my knees don’t like being still and in the cold for very long) and my little dog (who went to sleep under the blanket and acted as a living hot water bottle!) and watched the show.
There wasn’t as much activity as I thought there would be but what there was was quite spectacular as a lot of the meteors were fast moving and left trails behind them. A lot of the trails were green, although there were a couple of yellow/orange ones as well. The meteors were, for the most part, bright although there were a few quite faint ones as well.
As well as watching the show, I also had a look round Cygnus, Cassiopeia and Cepheus with my 8.42 binoculars. NGC 7000, the North America Nebula, was bright and the nebulosity extensive. The fainter Pelican Nebula, IC 5067/5070, lies just to the south of 7000 and is, just, visible through the binoculars without the UHC filter. With the 2″ UHC filter it is much easier to see.
I also found the planet Uranus, which is close to Jupiter. It looked like a small blueish-white star.


We have had a few decent observing nights recently, despite the continuing unsettled weather. The long hot days of late June have long since gone, to be replaced by cool temperatures, showers, more prolonged spells of rain and some fairly strong winds, but, so far, out of 12 nights this month we’ve had three completely clear nights and five partly clear, observationally-usable nights and early mornings so it’s not all bad, although I am also a fan of hot sunshine, something we’re not getting (I know, it’s hard to please some people! 😉 ). I have a feeling that, now it’s mid August, we’ve probably seen the last of any decent hot summer sunshine.
The reason for yet another rubbish summer, for the fourth year in a row is, yet again, the jet stream is too far south. Because of this, Russia and most of Europe are incredibly hot (although I don’t envy the Russians their severe fires, the downside of prolonged hot weather) yet Britain is damp and horrible – again. Sometimes, I get the impression that the British climate is doing this to amateur astronomers and holidaymakers:

Actually, I think I’ll blame the water company who imposed a hose pipe ban in part of England back in July. It’s in the north west of England, so hundreds of miles from here, but as soon as the utility company in question imposed the ban, the weather over the entire country turned bad.

Observing 7th-8th August 2010

The night of Saturday 7th August into Sunday was clear, although not as good as the previous Wednesday, so I pulled the scope out for a session looking for some summer Herschel 400 objects.

Conditions:
Clear, fairly warm, around 15C
NELM 6.0
Fairly humid with quite a lot of dew
Seeing II
Transparency II
Equipment: 12″ f5 Dob, 35mm Televue Panoptic (43x), 22mm Televue Panoptic (69x), 15mm Televue Plossl (101x), 11mm Televue Plossl (138x), OIII, UHC

NGC 6834, open cluster in Cygnus – irregular, attractive cluster made up of a line of 5 brighter stars crossing an elongated haze. At 138x, most of the haze resolves into faint stars.
There’s a separate clump to the immediate south of the main cluster, a knot of 10, or so, stars and another to the north, which has six stars.

NGC 6866, open cluster in Cygnus – Large, irregular cluster. Two chains of stars extend out from centre, one to the west and the other to the right. the western one is short and contains 7 brighter stars plus fainter ones. The eastern chain is longer and contains > 15 stars in a looping pattern.
There is a wide pair to the south.

Went after NGC 7044, but this was in the ‘dob hole’ and awkward to get at. One for another night, further into autumn when Cygnus is more to the west and that part’s easier to get at.

NGC 7027, planetary nebula in Cygnus – not on the H400 list but I was in the area. I am not sure why I found this easily and not 7044, but then a PNe’s easier to recognise than one of the myriad of open clusters and knots in the Milky Way in the Cygnus area.
7027 could easily be overlooked as just another star, as it is star like. However it isn’t stellar as at 69x it looks slightly fuzzy and an OIII filter makes it really jump out as a PNe.
At 138x its oval with no obvious darkening in the centre.

NGC 7296, open cluster in Lacerta – quite small, but conspicuous cluster near Beta Lacertae. Some stars resolved at 69, more resolved at 101x.

NGC 7243, open cluster in Lacerta – large, irregular cluster which fills the field of view of the 22mm Panoptic (69x). There are at least 23 brighter stars and many more fainter ones. Nice.

NGC 7209, open cluster in Lacerta – large and quite bright. Around 40 to 50 stars resolved. A very vague, rounded ‘m’ shape.

I finished up with a trip into the North America and Pelican nebulae, using my 35mm Panoptic and 2″ UHC filter. This was lovely, with wisps and and tendrils of subtle nebulosity everywhere. Here and there, hard edges were defined. Very nice indeed.

The next morning I found that, as the air heated up in the morning sunshine (Sunday was a hot day) my mirror had condensation on it. This is not good as repeated dewings up will cause the coating to deteriorate and fail and I don’t want to have to pay out for a recoating before I get my 20″. I opened up the scope and left it to dry out in the shed, with the shed doors open.
I posted on Cloudy Nights, asking how I can prevent this and most responses involved rigging up some kind of heating system. I am going to have to pay out for a car battery, an inverter and a lamp in the first instance and then, when I can afford it, a solar panel, at least 70w. However, a cheaper solution might be a large power pack with built-in inverter. That should run a low-watt lamp for a few hours to keep the mirror dry while the outside temps rise, although I am not sure exactly how long the charge would last, although some of these machines are pretty heavy-duty things. In the meantime, I have packed a couple of socks with silica gel and hung them inside the tube near, but not on, the mirror, then sealed the scope at both ends. I also went to Sainsbury’s and bought a bag of silica gel (not clay) cat litter which I’ll decant into socks and then hang inside the scope, tomorrow. Considering that quite a few of my socks have conspired to vanish, leaving only odd ones, they can do something useful! I blame the black hole that must be lurking somewere in the washing machine. The silica gel cat litter idea was also suggested on CN, stuffed socks and beanbags are the preferred method of holding them although, apparently someone once used a stuffed animal. WTF??!!

Website

I’ve just rebuilt my website on WordPress as I decided to go for a nice modern look and bin the Dreamweaver-built site. I have to start up my Win XP laptop every time I want to do an update, as my old Dreamweaver won’t work on Win 7,and it’s a drag, expecially as the wireless internet no longer works on the laptop.
I have just pointed the domain name away from the old site and at the new one and as domain changes propogate through the net at the pace of a paralysed snail it’ll be a while before the changes take effect. I just hope it works. The previous site will still appear for a while, until the changes, if they work, take effect.

Ok, things seem to have worked as www.fjastronomy.co.uk brings up the new site (it has to have the www in front of the domain or it won’t work).

New link: www.fjastronomy.co.uk Let me know what you think!

Observing 4th August 2010

A day of intermittent heavy rain and thunder gave way to clear skies during the evening, for once exactly as the forecast had predicted. The BBC and Metcheck’s forecasts both agreed, which seems to be a rare event in itself, so as it got dark I went and unlocked the observatory (I like the sound of that!) and pulled the scope out.
Earlier in the evening I had been in a pretty awful mood, no reason just a bad day, and felt more like saying ‘sod it’ and going to bed but I am very glad I didn’t as the sky turned out to be magnificent.
All too often when you step outside and look up, what looks promising at first often proves to be pretty average, even poor, but not last night. After getting dark adapted, I checked the naked eye limiting magnitude, using charts of Ursa Minor and Cygnus, and it was better than 6.5! We have pretty dark skies here, but better than 6.5 is fairly rare. Usually we get between 6.0 and 6.5 but last night was as good as 6.7! I would guess that the heavy rain and thunder had cleared the atmosphere of pollutants and dust. During my trips to the TSP, I’ve seen people using ‘iridescence’ in the Milky Way to gauge transparency – the more iridescent the MW, the more transparent the sky. The Milky Way was just like that here last night, iridescent, which we rarely see because of summer haze. Visible to the unaided eye were M13, M31 (later on when clear of the trees) and NGC 7000, the North America Nebula These were truly great summer observing conditions and well worth the long wait for.

Conditions: Clear, quite chilly
Seeing: Very good: Ant II
Transparency: Excellent – I, but a few odd bits of drifting cloud later on
NELM: 6.5-6.7, dropping slightly when the waning crescent Moon rose later on

First was Aquila and a hunt for the few Herschel 400 objects (three) that are here:

NGC 6781, planetary Nebula in Aquila – Set in nice starry field this is large and oval and quite bright. It’s easily seen without a filter but my OIII brings it out nicely. With the OIII, the pn looks slightly rounder with some darkening in the centre, without the filter I can’t see the darkening very well. Very nice object. 69x, 101x + OIII

NGC 6755, open cluster in Aquila – An attractive, small, compressed cluster set in a nice Milky Way field. Stars all white and evenly bright. Found at 69x as a misty knot, detached from MW star field.
101x shows a tiny, vaguely triangular clump of stars, with around a dozen or so on a hazy background and with a fainter patch next to it but at 138x, the cluster looks like a butterfly with the left wing richer than the right one. Very pretty! 69x, 101x, 138x

NGC 6756, open cluster in Aquila – Next to NGC 6755 in the field of view of the 22mm Panoptic (69x). It’s half a dozen stars on a misty background. Not as rich or as compressed as its neighbour. Framed by a bight star at either end. 69x, 101x, 138x

I saw on my star charts that the globular cluster Palomar 11, also in Aquila, was nearby, and given the excellent conditions I decided to have a crack at seeing it. After quite a few false starts I eventually found it. It’s in quite a rich area and nailing it down was a bit hard. It appears as a roundish brightening of the sky. Its low surface brightness and location in quite a rich part of the sky made finding it difficult but I caught it eventually. The observation of the night, I think. 69x, 101x, 138x, 190x

I also decided to see if I could see ICs 59 and 63 in Cassiopeia. Given the great night it would have been a shame not to go for the faint stuff.

IC 59, IC 63, diffuse nebulae in Cassiopeia – These faint little buggers are right next to Gamma Cas, so it’s necessary to put that out of the field of view before attempting to look for them. IC 59 is a faint fan-shaped patch while IC 63 is fainter still – in fact I barely saw 63, just a mere brightening in the area. 69x + UHC filter.

M31, galaxy in Andromeda – this lovely piece of eye candy is one of my favourites to look at and I always drop in to say ‘hi’ when I am observing and M31 is high enough. Last night’s conditions gave me the best telescopic view I have ever had of this galaxy. Under average skies usually only the bright central area is visible but last night, I could see (using my big 35mm Panoptic, at 43x) the galactic disk spreading out across and beyond the field of view, and the dust lanes. It was spectacular, to say the least.

NGC 6229, globular cluster in Hercules – Very bright and easy to find (made a nice change from Pal 11 and the faint nebulae in Cassiopeia!). Small and round with a dense core at 69x.
At 138x, it began to look granular with some stars resolved, especially the outer ones.
At 190x, individual stars can be seen and the halo and core are very bright, still looked granular across the face. 69x, 138x, 190x.

NGC 6207, galaxy in Hercules – bright and easily seen at 69x. It is completely overshadowed by its big and bright famous neighbour, M13. Oval, with a brighter core. Elongated northeast-southwest. 69x, 101x
I also popped over to see the big showy eye candy neighbour, which was absolutely superb as usual and in the same field they make a nice pair, with the galaxy being a hidden treasure.

Before packing in, I dropped in on Jupiter, which was shining like a big searchlight in the eastern sky, as the seeing was so good, and it looked decidedly odd without the South Equatorial Belt, which has totally faded away.

By 0200, the waning crescent Moon was substantially interfering with the sky conditions and there was more drifting cloud around so that, along with the fact my feet were by now very cold (I was wearing thin trainers) made packing up a Very Good Idea. So did the prospect of work in a few hours. So within five minutes, I’d pulled the scope back into the shed, chucked my charts back in their box, gathered up my eyepieces, locked up and headed back to the house.
As mentioned in my previous post, I’d found that the addition of wheels made my scope eyepiece higher off the ground. I knew it would be higher but not *how* higher. Consequently, viewing stuff at the zenith required standing on tiptoes. This was awkward and uncomfortable, as it hurt my calf muscles and toes, so some sort of small stool was a must. I found a little plastic step stool in Tesco this afternoon, for £2.50, which will fit the bill nicely.

First light in the observatory

The new observatory has now been used for the first time. We’re on a run of crap weather, very unsettled with showers, high winds, the odd sunny spell and almost totally cloudy nights, so observing opportunities this summer have been non-existent (typically, the best weather this summer was at the end of June when the summer twilight made serious deep sky observing impossible or, at least, very difficult). However, last night was an exception, although it wasn’t very clear and there was quite a lot of cloud about.
I’d already carried the scope up the garden and installed it in its new home so it was just a case of wheeling it out and then back in at the end of the sessions – it makes life so much easier and I very much doubt if I’d have even bothered last night if I’d have had to carry the scope from the house and set up.

Here’s the inside of the observatory shed, with the 12″ under tarpaulins (these will give it that little bit of extra protection *just in case*), folding chair, box containing star charts, atlases, gloves, hat, torches and sketchbooks, my dog’s basket for her to curl up in as she always comes with me when I observe and some pictures on the wall. I also have a couple of shelves for bits and pieces. However, anything of real value, apart from my cheap reflector which isn’t worth nicking, such as binoculars and eyepieces, are staying inside the house and any potential thief wanting to lug a large and very heavy scope down the garden, past some stranger-loathing dogs and out the gate is an idiot and deserves to be arrested on grounds of stupidity. The photo’s a bit distorted, that’s thanks to the 17mm end of my wideangle lens and not because of my construction abilities!

The day before yesterday, I fixed the casters to the blocks that I was going to use to attach the wheels to the base. I bolted the wheels to the blocks using bolts, unfortunately two of the bolts sheered off rendering them useless but the rest went on ok. I just hope they can stand up to being wheeled over rough ground every clear night, as the top lawn isn’t the smoothest, what with the mole hills and vole holes, etc.
I then fixed the blocks and wheels to the base using ‘No More Nails‘, which is a type of glue which is supposed to be strong – it’s the sort of thing you see the ads for where someone’s used this stuff to put shelves up and the ad shows a man sitting on the shelves to ‘prove’ that it’s strong and won’t come unbonded (in reality, it ain’t *that* good; if it was, the soap dish would stay fixed to the bathroom tiles). I let it set overnight, for the recommended 24 hours. However, as soon as I put the rocker box on top, the wheels promptly fell off it- just like they’d fallen off my clever idea – although, fortunately the scope itself was still sitting in my room and therefore didn’t come to grief. So it was time for a rethink, which didn’t take long as it was a case of having to screw the wheels to the base. We have electric drills but I couldn’t find the drill bits, so I went across the way and borrowed our neighbour and his battery-operated drill and, between us, we got the wheels (hopefully) securely fixed to the base. Quite why I thought ‘No More Nails‘ or any sort of glue was a good idea, especially in light of our laws-of-gravity-proving soap dish, I have no idea! I think I was trying to do it the easy way, or so I thought.

Back to the quick observing session, I wheeled the scope out, collimated it and got going. The beauty of the scope being out in a shed is that cool-down times are very short and, except on hot days/nights, practically non-existent. Because of the lousy conditions I didn’t do a lot, just poked around, looking at NGC 5653 in Bootes, M14 in Ophiuchus and NGC 7006 in Delphinus. I did find, however, that the addition of the wheels and blocks raised the height of the scope by several inches and that I, and I’m not short, have to stand on tiptoe to see anything at the zenith, which is not very comfortable for extended periods of time, making prolonged observations difficult. I need to get a short stepstool for that.
I also didn’t have an observing table for my charts, etc, so I had to use the floor and, with my dodgy knee that wasn’t comfortable. I have ordered a 4ft folding table from Amazon and that should turn up tomorrow. When I observed from the patio I used to use the kitchen extension as an observatory and the top of the small chest freezer as a chart table. That is no longer practical as I am so far from the house, so the folding table should do nicely.

Conditions: Cool, no dew.
Seeing: Very good, Ant II Transparency: poor, with high clouds
NELM: 6.0, falling to 5.8 when the last quarter Moon rose, washing out the sky.
Instrument: 12″ f/5 Dob, 22mm Panoptic and 15mm Plossl

NGC 5653, galaxy in Bootes – a poor view, due to lousy sky conditions. I could just make out a roundish smudge, not a lot brighter than the background sky. Haze was interfering with this quite badly, as was the low altitude of Bootes. 69x, 101x.

M14 (NGC 6402), globular cluster in Ophiuchus – very large and bright. Round. Some condensation towards the centre. Looks smooth when looked at with direct vision, but granular, with a few stars resolved, with averted vision. The scope was effectively reduced to 6″ by the hedge – I’d not set it up in my intended place. 69x, 101x

NGC 7006, globular cluster in Delphinus – small and bright. Round with bright core. 69x, 101x. I want to observe this, likewise NGC 5653 in Bootes, in more favourable conditions.

By this time, the clouds were worse and the rising last quarter Moon was interfering with observations, so I rolled the scope back in, put my charts away and locked it. It took me a fraction of the time it used to take to both set up and put away, before it would take me a good 20 minutes, maybe more to tear down and carry everything, including the scope, inside, now I’m indoors and heading for bed within 5 minutes! This will lead to many more observing sessions and, as I said at the beginning of this post, observing under less-than-favourable conditions and/or when tired will now happen far more often. Not only that, I have far more space inside my bedroom as the Dob occupied too much of the floor.
