About
A four-element multicoated 40 mm lens in a metal cell that threads onto the rear cell of Celestron and Meade Schmidt-Cassegrains, turning an f/10 scope into an f/6.3 (and the f/11 C14 into an f/7). It duplicates the telescope's rear-cell thread, so standard visual and photographic accessories still attach behind it.
