Actually that is a very old sketch and I think I did that using a 76mm newtonian. I did a very detailed sketch (took me 1 1/2 to 2 hours to complete) using my C6 at different mags to get a composit ala O'Meara. Problem is it does not scan out very well. I might have to make a copy of it (doing it bolder) so I can get a good scan. Will post when I get it done.
