Wonderful information Greg, thanks. Alot of the recent discussion on Milky Way, ie ultra wide field lenses covers that area. But what i was trying to ask was about equipment around the cross over pont between lenses and small APOs. For example scopes like the AT65EDQ, at 400mm focal length, or the TS Photoline 60mm at 330mm focal length, both of which have good optics and are very cost effective. Compared to the various DSLR lenses in that focal length reach.
