The The Moonfish® 15mm 80° ULTRAWIDE is yet another serious wide-angle 2" eyepiece, at a price that's more affordable for everyone. In common with its bigger brother, it offers good contrast and correction.
The eyepiece has six elements of fully multi-coated (FMC), high-index glass, with a high light transmission, allowing your telescope to be pushed to its magnitude limits. Field correction is good, although edge performance does begin to soften, very slightly, when used with short focal ratio telescopes, i.e. much less than F/6. The weight of the eyepiece is surprisingly low for a 2" design at 'only' 260 g.
Each eyepiece is carefully quality tested before shipping. The barrel is fully threaded for 2" nebula filters, has a rubber grip, and comes with an end cap.
