We're finally getting some good weather for astro. Last night was very crisp. Temp was down to 9 degrees at my location. Here's a reshoot of NGC 3532. I like this one a lot better even though its from just three exposures. I think I got good focus with these three subs.
Subject: NGC 3532 Open Cluster in Carina
Exposure: 3 x 30 secs x 1600 ISO
Lens: 200mm f2.8 Canon @f4.5 unfiltered
Camera: Canon 350D Unmodified
Mount: EQ-6 unguided
Date: 18Jan2009
Yes! nice widefield shot of this cluster.
I know my 200 2.8 is real touchy to focus. Even auto focusing on a bright star it still needs to be tweaked a little to get it right.
cheers Gary
