I have a 5" F/6.5 refractor that can be used as a guidescope. The
cosmetics are very nice (powderocated Astro-Physics white) and the lens
coating is excellent; but the performance is poor. Typical Chinese quality,
secondary color and can't hold high power. It's a good beginners scope,
has a 2" focuser; but needs a 2" extension, not included. At this price of
$ 150.00 plus shipping, the sale is final.
