If you dont wear glasses, and dont mind the 50 deg FOV, these are the best plossls for the money out there. Excellent edge to edge sharpness, good contrast, and brightness, with zero negative aspects when used in my 80mm F6 WO refractor. I bought the set of 15mm, 11mm, and 8mm and all are HIGHLY RECOMMENED with the only reservation being the 8mm has very short eye relief due to the nature of the plossl design.
This plossl gives excellent detail and pinpoint accuracy on Planets and Nebulas. Its optics are well coated and it appears to give brighter views than most other plossls Ive tried. My only reservation is the usable eye relief... but most EPs at this price and focal length have the same issue. If you need more eye relief and dont mind spending a little more, I recommend the Celestron Vixen Lanthanums.
