hey there mate,
I have the Bintel (rebranded GSO) version of the ED barlow, and im quite happy with it. with the 10" SW + 10mm EP and the ED 2x Barlow i was able to view things like M1 (crab nebula) also venus/jups/saturn which was very nice. If you are doing visual, you might want to get some nice good quality collimating tools this will make your life a breeze and give you that extra 10% where the details really start popping out.!
