Description:I purchased this scope used in 1963, Cave Optics in generic fiberglass Tube on massive 12.5" (2" steel shafts) Star Liner Mount with H&W Optical Clock drive. It has been a great preformer over the years stars show 4 spikes from secondary holder but are sharpe and bright, but with slight coma near the edge of the feild, it has good contrast and is rock steady on this mount. One of the few telescopes I've seen that is overmounted. Steel shafts turn in bronze and aluminum bushings, very smooth. It has been updated with a Meade 9x60 RA finder, JMI NGF DX3 focuser, rotating tube rings of my own design, Litghted and magnified pointers on 6" setting circles. Next project is to motorize dec axis and to add a drive corrector. The tube is somwhatlarger than it need to be and at over 200lbs it's nmot very portable, that's my only complaint. I rate it as a 9.5

I recently picked up a 10" F/8 cave OTA and mounted it on an Optical Craftsman mount. Great pairing and at less that $1000 overall, a killer in terms of cost per performance. On planets and the Moon it will run circles around smaller APOs, providing crisp, detailed images. Downside: tube currents can be annoying, cooling and good collimation are a must. And it is a pretty large package to deal with. But tracking, stability and overall ease of use make it a winner!
