It has a very small chip on the mirror, but it does not effect the performance. I didn't notice it until I disassembled my camera setup.

Hi Ben, I'd be interested in buying your OAG. Does it come with all the fittings etc the unit did initially when new?

Cheers, mitchell

I just checked and managed to find all the adapters

Hi Ben. I'm couldn't find any details online about the prism size. Are you able to take some quick measurement of the pick up prism dimension?

I'm contemplating whether this is a worthwhile upgrade over the regular ZWO OAG and my guide camera. Thanks!

I actually moved form this to the ZWO OAG and didn't notice a performance improvement. I did this because the ZWO has the very handy focuser attachment for the guide camera.



The Orion is good when you don't have much back focus to play with. I originally got it so I could use a DSLR on my newt.
