Hi guys,
I am looking for a webpage, a magazine or a book that has pictures showing reflector telescopes performance comparison based on a primary mirror aperture. I am looking for pictures that are real through-eyepiece views or are processed the way to show the view using aperture of 6", 8", 10", 12" and so on.
Thanks in advance smile

If you do an internet search on 'Messier Sketches' you will find a number of interesting sites where there are hand sketched views by various amateurs. Here is a link to one site where the author has used a 10" SCT. There lots of others that may help you find what you are looking for.

have fun,
dan

I know these are not actual pictures but it will give a computer generated approximate view that you can change the scope specs. so you can get an idea of the differance between scopes.
