I have an 80 GT mount that I used with my Borg 76ED refractor as an inexpensive, quick grab and goto. Other than strategically velcro, can't tell from new. Updated hand controller works perfectly, very accurate goto, alt/az (for visual use only, unless you want to do a little quick exposure solar photography). OTA is 80mm, f/5, great as a finder too. Nice smooth focuser. Optics tuned up and are nice for Chinese achromat.
Mount only: $195 plus shipping (about $15 USPS 2-3 day priority)
Complete package with OTA: $250 plus shippping (about $20 as above)
If you take the OTA, I'll throw in a home-made solar filter made with Baader visual solar filter film. Works great, nice contrast.
Baader bracket in picture is sold. Works very well with a Baader, can add any scope up to about 10lbs (ETX 90 or 105; 70-100mm ST refractors) and mount will be accurate and not overtaxed. A lot of fun for the $$$. Thanks.
