Celestron C-14 (black) optical tube assembly with Starbright coatings for sale for $3200 plus shipping (from Los Angeles). It has good optics and very little usage. Several photos taken with the telescope have appeared in SKY and TELESCOPE as well as one on the cover of ASTRONOMY. If you e-mail me I can send you an URL so you can see a photo taken with this telescope at its prime focus of f/11.
The tube has both a Losmandy dovetail mounting plate and Shaefer radius blocks (these can be removed if desired). The Shaefer blocks are the same type used by Tony Hallas for his 14-inch telescope. They could also be used for mounting to any flat mount saddle. The tube also comes with a giant Celestron 2-inch star diagonal, straight thru 80 mm finder scope and 35 mm camera piggyback mounting plate.
I also have an 80-mm rack and pinion finder scope with custom mounting bracket for the C-14 that I could sell for an extra $200.
