GSO 12 inch mirror
GSO 12 inch F5 mirror. The surface has a few blemishes but the coatings are still very usable. Very cheap entry into decent aperture for someone willing to put together their own OTA. Excellent back-up mirror if you're in the habit of dropping yours. :-)
$100 + postage if required.
