It's kind of funny, but I knew that I'd get to a place where I only took one image in a night. That may have been different tonight since the night is so long right now, but I didn't get started until 11 pm.
While our astronomy meeting was going on and I was enjoying the observing (as it was a clear night on a meeting night) and discussions, my camera was in my driveway getting chilled to the bone. By the time I got back to my place, the Peltier Chamber was -16F (rats... I should have been taking darks during that time... oh well). That's quite a bit colder then I've ran it before. The first shot from the camera was -1.4F, the next few were 5F and the camera finally stabilized for the rest of the exposures at 9F. My coldest recorded temps before that were 21F. It's fun to have a Peltier Chamber!
So, I decided to shoot NGC 4565 as it was at a good spot in the sky and I was hoping for 2 primary specifics in the outcome:
1) The camera running so cold to produce a much smoother image then I normally get - without smoothing it in de-noising processing techniques that is.
2) The sharper optics in the Vixen ED103s would give me better detail in the already amazing dust lane.
It didn't turn out half bad and definitely my personal best on this incredible target.
