I'm cleaning out astrostuff. Sold my SCT and still have some SCT photo items:
Celestron 1.25" off axis guider $30 + shipping
0.5x telecompressor for 1.25" off-axis guider or back of SCT - one is fine and one has some streaks or scratches - $50 for both + shipping
1.25" prism diagonal - some say "vintage", some say "rare", I say old. The kind with the slip-in tube for eyepieces rather than thumbscrews. I have an extra body and prism - the prism has an edge chip (but it isn't visible when inserted into the diagonal) - $15 for both + shipping.
Please feel free to e-mail with questions.
