This reducer has a shorter focal length than the Meade3.3, so you don’t need a spacer between the reducer and the camera. It just about gives the full x3.3 reduction when screwed directly in to my ASI224MC and an ASI290MM cameras which have a backfocus of 12.5mm.
Please note: like the Meade3.3 these were made to be used with small 1/3” sensors. I’ve used it with an ASI224MC and an ASI290MM on a C8 SCT and my 80mm refractor.
$135 plus postage, ono. Please PM if interested.
Thanks, Chris
