Btw, just to clarify, I wasn’t explicitly advocating a 12” newt, they are a beast(!), although Glen’s mount would be fine with it I’m sure.
My gut feeling is a little more mid-size, say a 10” f/5, as Glen already has an ASI1600 camera, which combined will give a resolution of about 0.6”/pixel.
May sound like a compromise, but an economical, easy(ish) to handle, easy(ish) to collimate compromise
