If you have received your mount but are still waiting for the refractor - this might be a good choice in the interim. It was for me. Sold by Orion in the late 1990s, this Maksutov Newtonian made by Intes in the Ukraine has a very small secondary obstruction and provides excellent contrast with performance similar to a refractor of equal aperture. And it costs less to buy than the resale hit for trading in a second choice APO when the first choice arrives.
Included are tube rings with top plate and (if you would like it) 7" sliding bar to fit Astro-Physics dove08 dovetail plate, 50mm finderscope, 2-1.25 adapter, and a custom foam wrap and soft case that I use to transport the scope. All caps are included - the condition of the scope is excellent. Please note - A/P 600 is not for sale. New it was $1100.00 - asking 675.00 plus cost of UPS ground shipping. Paypal accepted.
thanks for looking!
