Once in my browsing... I found an image showing various space objects and how big they looked through the same telescope ie all on the same image scaled the same...
this really gave a great idea of how big or small things are... I didn't book mark it though.. and have never been able to find it again... has anyone seen something like this?
from memory it had Jupiter,Saturn Andromeda, Mars, Moon and more all on the same image...
Just found these, they maybe a start. Scopesim comes close with a few planets, deep sky objects. No doubt others will have their favourites, in fact something like this would make a good sticky Mr Moderators.
Just remembered CCD calc is a free programme that is useful for using with various ccd cameras and dslr cameras. Not quite what you want right now but useful down the track and as it's free you can't go wrong! http://www.newastro.com/book_new/camera_app.php
