saxon/gso/skywatcher/orion there all good, an 8" is better but cost alot more and i found the 6" to be my love. Most 6" dob are f8 ect against a 8" is mostly f5, people forget that fact and all say 8". A 6" hold colimation much better and is much more forgiving and easy to collimate over a f5, another fact people forget. To many people jump on the train here without looking at the ticket some days. I found the 6" my favorite visual scope because of collimation/weight/easy of picking up and going, the dam 12" goto truss skywatcher which we got to replace it mostly collects dust, yer it gives unreal views but hell i just can't be bothered lugging the dam thing outside.
