2Ē WO dielectric diagonal (Durabright)
27 January 2023  | 

Lovely looking diagonal that is well made and high quality. I fitted the SCT adapter for SCTís onto this diagonal and they complement each other great. Optically I have only managed one observing session, but the seeing was really poor so Iím unable to comment on the optical performance. Knowing Williams Optics, I reckon itís going to be good. Great service from FLO again.

Really impressive quality diagonal
16 December 2021  | 

Bought to replace the cheap plastic diagonal that comes with most scopes, a lot of beginner telescopes are dismissed as rubbish or useless but when you upgrade the diagonal and eyepieces its surprising how much it improves the experience.

This is a top premium product that will last and once purchased it can be used for future telescopes you buy.

Flo are fantastic, never had a bad experience with all the items I have bought, highly recommend.

The first thing that hits you is the build quality and in use with my 250mm SCT gives views of outstanding clarity free from the slight tinge of the item, (approx 10 years old), which it replaced. I'm delighted with this upgrade.

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

Quality piece of kit
11 May 2013  | 

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
12 March 2013  | 

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.
