Up for sale is a classic 80mm f 15 Sears Discoverer Telescope on a Super Polaris GEM & pier. The OTA comes with the original 6X30 finder and a Celestron 0.965" diagonal. The lens cell is an adjustable three point push/pull type and the lens is in like new condition with the original lens cover. The scope delivers a textbook diffraction pattern and on stable nights I have easily surpassed the 75X aperture envelope with this scope without image break down. No eyepiece with the scope. The OTA is mounted on a like new Super Polaris GEM (= to CG4 GEM) with polar alignment scope & motors on both axes. Placed a 102mm f11 refractor from Sky-Watcher on the mount this weekend (2012-09-15) and the mount carried the extra weight without any issues. I "hyper-tuned" the GEM for visual use but with a little more adjustment the mount can be used for beginning astrophotography. The GEM mates to a very stable three leg pier (steel & aluminum) with adjustable turnbuckles very similar to those used on ASTRO-PHYSICS piers. I also have the slow-mo manual knobs, hardware & user manual that came with the GEM. This package is the best of the old and the new. Whole package price $299.00, Paypal add 3%. Boxed and ready to ship. Shipped to Cont USA only.
