Finest hand-figured optics available. Manufactured in Discovery’s own state-of-the-art facility in the USA. This set of optics was hand selected Terry Ostahowski from one of his 35 mirror runs. (Note: Terry is one of the founding partners of Discovery and the optics guy. He has now started his own optics shop in Anza, CA). They were painstakingly tested until they passed strict standards for diffraction limited and incorporated the use of Fizuea, Equal-plate and Scatter-path interferometers. Enhanced Aluminum primary coating and Endurobright coating by QSP on Secondary. Optics are exceptional – Ronche Test looks perfect and the in and out of focus excellent per Tony Hallas (world famous astrophotographer who evaluated this telescope).
