Check the listing for details. 8” Telescope Blank and Pitch Lap. Condition: For parts or not working. Listed at 275.00 USD. This mirror was ground by me at a Carl Zambuto workshop many years ago. I vaguely recall this a f8. It is close to final but I could not finish with Cerium Oxide to a perfect parabola, as measured by a Ronchi test. I expect it will require backing up a grit, then proceeding to Cerium. The lap, made with Gugolz pitch, will need to be recast, as it has flowed. Work was done under direction of Mr. Zambuto, so all materials are top-notch. If you have followed this and know your way around a Ronchi test, this is for you. Likely quick to finish but my momentum is gone.
