Hi there, I purchased this to help me focus my 9.25" SCT, and used it a few times but found that it's too long for my Evolution alt/az mount, and the camera/diagonal comes into contact with the base at high altitude angles.
It's basically a re-badged GSO unit, can be used for 2" or 1.25" eyepieces and is in perfect condition, it's just sitting here unloved and unwanted.
Price $100 + $10 express postage to anywhere in Australia.
