Is it a good product and does it give better results than a regular OAG?
66mm of back focus and having the camera off to the side rather than at the end seem a minus (does it cause balance problems?).

Greg, I recently purchased one, but as I am still setting up my new pier and mount, haven't yet gotten around to trying the ONAG in anger.
Just a small clarification regarding the camera position; the imaging camera actually screws into the "top" of the unit, with the guide camera attaching to the rear via a crude focusser. Obviously the whole unit can be rotated in the attachment to the scope, so yes, you could have the imaging setup to the side, but I imagine most would set it to be at the top, for the better balance.
My plan is for DSI II mono guide camera at the rear, and QHY 8 Pro OSC or QHY9 Hlrgb with filter wheel on top. Happy snap of initial trial attached.
Might do a review when I get it all together.
Mike
