The eyepiece is well machined and the glass is really good. Nice eye relief. I viewed the moon with a 3 inch f15 refractor at 160x, the clarity and contrast are excellent. I took a star away because the eyepiece is not threaded for .965 inch filters.
Finally got to use this the other night on my Unitron 128. A nice clear medium-high power view of the Moon. I wish a 6 mm 0.965 Antares Plossl was available.
