What will it look like ?

I am looking for some web links that will show what diffrent size scope can resolve for there aperture.
Thanks for any help you can pass on.

Here's one of the better sites. http://clarkvision.com/visastro/m51-apert/ .

I'm toying with the idea of doing some comparisons with a 10" Dob and a diminutive ETX.

Depends on seeing conditions, dark adaptation of the eyes, etc. Averted vision helps in a lot of cases.

Won't look anything like the mega exposure pictures, but doing is much funner.

Here's a link to a simulated comparison of M13 at various apertures on the Obsession telescopes website. If you try to access the Obsession telescope website, be sure to use Obsessiontelescopes.com and not obsession.com as I just did. The results of the latter are x-rated and not spousal friendly. My wife did not believe me when I told her I was looking for telescope info.
