I am looking for a good quality Barlow, for my newly bought F4.7 scope, an Orion XT10i (10inch Dobsonian).
As this is a fast scope, I am searching for a good quality Barlow to be used combined with some good quality eyepieces (they will be either ES68 or used Televue). The scope only came with two Plossl 25mm and 10mm.
I heard good things of the 1.25" Orion Ultrascopic Barlow 2x. Any experience with it?
Is the Celestron X Cel Barlow also of good quality? Would the 3x be equally good?
