The other disinclination for me (apart from the weight/backfocus/price) is the necessity. With a TOAG and ASI120MM, I've never had any backfocus issues and never failed to find a guide star (I've never even needed to do any lateral movement to the prism stalk!). Sensitive guide cameras with QE in the mid-70%s are awesome
But it's horses for courses, and it's terrific that this has helped you Eden. Happy imaging!
