I just fitted the ZWO EAF to my C8 (not edge) and despite absolutely ZERO fitting instructions it's working fine

 

Link below to the YouTube video that explains the installation - a life saver

It seems to be one of the cheapest options out there. The (non) optional fitting bracket says the Edge is compatible

I ordered the bracket separately for mine (Agena I think).  Followed the video just as above and it was easy peasy, up and running in 5 minutes.

The bracket is a separate order - as a side note - the allen key/wrench size for the 3 screws that replace the 3 original screws holding the original focuser ring on to the OTA are a weird size - I'm guessing imperial - you get 2 allen keys (metric) with the EAF but neither fit - luckily I own an American made guitar and had one that fits for that otherwise I would have been stuck. I also didn't consider my DSLR - I am now restricted to camera angle but that's not a big deal. Also, to balance on the DEC axis I am at the limit of my OTA dovetail - but again, got away with it - see pics below

 

As a side note - I ordered the old model EAF but received the new version (no power supply required) so that's a bonus!!

 

Clear skies tonight so hopefully 1st light for the focuser, but I have been using it in the house in daytime and have to say it's a great piece of kit
