Dob structure for star testing.
Recently threw together a cheapy Dob assembly to star test mirrors from 6"f8, 8"f6, 10"f5, 12 1/2" f4 (currently "housed") to 14 1/2" f3.6.
Construction cost was minimal as only used "stuff" I had lying around from
previous projects. Didn't have enough of same type of wheels for cart, so use a pair from a discarded child's toy for rear. Will get a matching
pair in due course.
