Interesting and enjoyable video from Ed as always. Hard to argue with logic of an 8” dob, especially when price and convenience is taken into consideration.
I’ve only used a limited range of scopes (basically those in my sig). They all have their pros and cons. The SCT is not so good on tight doubles (due to ‘hairy’ stars), wide field or solar. The 4” refractor is not so good on faint fuzzies and globs. The 6” Newt is not ideal for solar, wide field and theoretically not very flexible for binoviewing, which is a must for me when solar system viewing now. So none of them are the perfect all rounders. So what would I choose as my only scope out of my meagre collection? Given that my skies rarely get dark enough to see really faint fuzzies, and rarely get stable enough to allow larger apertures to outperform on planets, then the 4” frac is probably the winner in most situations, but to be honest, I would also be fine with either of the other two as my only scope, I would adapt my viewing to suit. 🙂
