I was wary of buying this as the description notes that it’s not suitable for Celestron Edge HD ota. However, after asking round I took the chance and can say it fits like a charm.
Look up Astroblender’s YouTube tutorial. It’s excellent and describes the installation step by step.
So far I’ve only tested it on the daytime moon, but I can’t fault it so far. I’d go as far as to say it provides a more stable platform than the Celestron motor which it replaces, and was certainly easier to install. Excellent!
Just need a clear night now to try it out ‘for real’.

Altho the description says not for EdgeHD it fits easily. Remember to leave the orange disc in-place. As I write this the scope is imaging and performing auto focuses with the AISAIR.
