Then hard pass OP.

You can get an 80mm achro on a questionable mount for far less...and have money leftover for a cell phone adapter to attach to the eyepiece for "live view" if that's what you're after. Or if you have the $400 this would cost check out the pinned guide at the top of the sub for tabletop dobs that will have way more aperture and be portable enough for balcony use and/or taking someplace darker to view.
