Thought I'd give the Viel Nebula a shot

I'll have to check that out. Thanks Chris. Unfortunately Starry night will still just have the oval in place of the object. Like on the Veil Complex it does not break it into the Eastern and Western. But still a good tool.

Celestron, hot did you come up with the FOV size. I know you said approx, but an approximate idea is what I'd like to have for new targets.


I started shooting film with a SLR film camera back in 2001 and my favorite lens was a 50mm for WF shots . What i discovered and learned was that the 50mm was just big enough to frame most all big constellations in the sky but some took less of the frame and some all the frame but i shot the summer triangle quite a few times and that's how i know a FF camera with a 50mm lens is equivalent to a SLR Film camera with a 50mm lens . Now i use a XSi with a 18-55mmIS lens and if i set it to 50mm the summer triangle does not fit inside the frame well at all because of it being a crop camera of 1.6x . So when i made the star chart for example i judged what size i thought a FF with a 50mm would look like . Look on my website DeepSpace (external link) and you'll see the first 3 images are taken with a Film SLR and 50mm lens and that might help you see what i'm talking about .

You can input sensor sizes and scope details into Starry Night and then get it to overlay the combinations of them onto the sky to see how the size works out. Really good as a planning tool.

Thanks Chris. That is a really nice feature I'd never messed with. Another good reason to be on these forums :D

Indeed :-) just remember to change which scope rectangle you are using in Starry Night when you go outside (the voice of experience in finding something didnt fit when it was rather too late to do anything about it :-) )
