Done my homework over a 6 month period on the Skywatcher 6” and 8” f5 scopes vs the Bintel GSO 6” and 8” f5 and f6 scopes for both visual and astrophotography

They both get the job done in their price category but I find the GSO focusers superior and the general build a bit better quality ( finish , hardware used , paintwork etc) Also the secondary and primary mirrors have better adjustment in the GSO

GSO use BK7 glass for their mirrors
Skywatcher use Pyrex which is a little more expensive
Personally I can’t see any difference

I have a Skywatcher 12” Goto Dob which is an excellent instrument for the money. Only reason why I bought a Skywatcher is that GSO don’t make a 12” Goto dob

I think from memory the Skywatcher 6” and 8” are slightly heavier than the GSO

I went GSO for my astrophotography rigs and Skywatcher for my big visual rig

Very happy with my decision

My 2 cents ....
