Are these two ota's basically the same? (speaking of the 80 ED models) thank you, John M
John: Optically they are identical, both use the same FPL-53 based doublet. Mechanically they are different. The Celestron has a OTA with a 90mm diameter and a rack and pinion focuser where as the Orion (and Skywatcher) has an OTA that is 100mm in diameter and Crayford focuser.
Stock, the Crayford focuser is significantly better than the Rack and Pinion and IMHO, makes the Orion version more desirable.
