This Skywatcher 9mm 1.25" Eyepiece offer an amazingly wide 58° apparent field of view and 20mm Long Eye Relief, rivaling some of the leading premium eyepieces on the market. It superb field edge correction and high contrast delivers an better experience while still being competitively priced. Expertly finished in anodized aluminum, it features knurled rubber grips and is threaded for use with standard filters.
However the eyepiece is well made and is clear to look through- Is hard to use with a Barlow lens as a kidney bean effect is present. But if one keeps their eye close to the center of view it's not noticeable- I don't recommend for people who wear eyeglasses when using Barlow.
Great for looking at the moon and planets including splitting double stars.
If you have eyepieces such as the Plossl, Huygens, Ramsden, Kellner or "Achromat", Orthoscopic or "Abbe", RKE and Monocentric, this eyepiece will not disappoint. There will be improved "seeing" and increased field of view.
BUT if you own Erfle, König or Nagler the seeing is good but the field of view you are use too will be smaller making this eyepiece disappointing. (Posted on Jun 25, 2013)
