Very pleased with my purchase and is much better than the standard diagonal that came with the SCT 9.25.

Quality piece of kit

I bought this diagonal a few weeks ago and have had the chance to give it a whirl with my new 2" Baader Quicklock and also my newly purchased Hyperion Aspheric 36mm eyepiece. The diagonal oozes quality. The feel and the build quality are excellent. It just has an all round fantastic sense of solidity to it. And I love the addition of the 1.25 adapter included in the price as well. It really performs well in my C9.25. All in all very please. Buy one yourself. You know it makes sense!!!!!

Outstanding Diagonal

This is an outstanding piece of optical engineering. I have a 6SE and was not happy with the stock 1.25" star diagonal. I have 1.25" eyepieces and this 2" diagonal allows me to use the mirrors central sweet spot for them. The supplied SCT adapter is a bonus as I still have an upgrade path to add a focuser when funds permit. Absolutely superb kit.
