Hi Everyone.  After many years I finally pulled the trigger and purchased an OTA upgrade from my old trusty Meade 8 Inch Classic SCT.  I got a good deal on a used EdgeHD 9.25" and am awaiting delivery with bated breath.  I have some questions though.  I'm wondering what the best reducer option is if I want to continue using my Moonlite CS Crayford focuser with the Edge.  It looks like nearly all of the back focus with be eaten up with the Moonlite + Celestron 0.7x reducer maybe not even leaving enough for my filter drawer and ASI camera.  Does anyone have experience with the Optec Lepus 0.62 HD reducer?  It looks to have a much smaller form factor than the Celestron reducer.  I'd be okay with the smaller imaging circle from the Lepus as my camera is a micro 4/3.  I also do know that Moonlite makes a specific focuser for the EdgeHD's but that's not in the cards right now and it seems they have serious supply chain issues anyway.  I've also seen posts regarding an EdgeHD version of the Night Owl from Starizona but it seems that product never came to fruition?

The backfocus on an Edge is measured from the back of the Celestron 0.7 reducer. On the Celestron website you can find white paper on the Edge covering details of the design and specifics of the backfocus.
