The weather recently has been clear, but murky, and last night was no exception. I went to our local society’s observatory last night (every Thursday is the open evening and we usually get a mix of members and sometimes interested members of the public) and we took out some scopes, including a 10″ Orion Intelliscope.
Unfortunately the mist and murk were worse than the previous night and we only were able to look at the brightest Messiers. Galaxies, as expected, were worst hit and even normally good Messier galaxies were almost obliterated. We did look at M105, NGC 3384, M65 and M66 (NGC 3628, one of the Leo Triplet with M65 and 66, was utterly wiped out by the murk), M81, M82, open clusters M93 and M46 (not a bad view despite their low altitude in Puppis and the misty conditions), perennial faves M42 and M43, plus the attractive blue and yellow double star Iota Cancri and, later when it rose, Saturn, whose rings have opened up since I last saw it.

I have never used an Intelliscope before. The concept is similar to the Argo Navis system, a digital setting circle. You enter your wanted Messier or NGC number, the display shows some numbers, which are how far you need to push the scope in altitude and azimuth to get to where you are going, along with arrows showing which direction you need to push the scope. The numbers get lower the nearer you are and when you arrive at the location the display will read 0<>0 0<>0. The society’s Intelliscope was a little off, with the objects being just out of the field of view, but not by much. It’s a neat system and I’d like a similar thing for my scope, maybe an Argo Navis, one day.

Despite the crap conditions it was a nice evening and we also spent the time putting the world to rights as well as observing. It was disappointing though, that only a handful of us were outside, with most people choosing to sit inside the building and chat. It’s an astronomy society, so it would be nice if everyone was outside but that seems to be the difference betwen UK and US amateurs. Over there, it seems to be a more vibrant and active scene.

Clocks go forward on Sunday morning. Yuck.
