Got this for an ATM planetary Newtonian project that never ended up materializing. Selling an exceptional Mark Harry 10" f/6 primary mirror (actual FL is 60.16"). 1.25" thick, and test documentation shows worst case P/V error at 1/20 wave (outer zones are noted as better than 1/40 wave), Strehl ratio of .99. Mirror coating is in perfect shape, has never been mounted or exposed to the elements, and has remained in its dust cover since receipt.

Asking $800 plus shipping. Mirror is very securely packed, but will only ship with direct signature confirmation. PayPal F&F, Zelle, Venmo, or cashier's check please.
