Some months ago, I was looking for advices and tests about an OAG (Off-Axis Guide). I’m mostly using my Celestron C9 with the Hyperstar so with a short focal length, and my guidescope FMA135 has the right ratio with the Hyperstar.

But as I started using a guiding system last year (got some issues with it), I knew that at some point I would need another system for long focal. I wanted to give some first light on a Takahashi Mewlon, and an OAG is mandatory. I found a blog testing the OAG from PegasusAstro (I’m a fan of this company) and it convinced me to get it.

We got in touch with Thomas few days ago, and I’ve put his website up there, just click on “Collaboration - Thomas”.
