The 12mm was a close second, but showed very slight field curvature at the extreme edge. > >The 7mm is my favorite for viewing small planetary nebula at medium-high magnifications. The eyepiece has excellent contrast and brightness for such a huge stack of glass. > >Star images are very tight, and lateral color is almost non-existant. (better than the 10mm SW, which does show a tiny bit of lateral color) > >Build quality is very good, but not on par with Televue, Pentax, etc. Watch out for dust on the field lens... > >NOTE: These comments are based upon my tests in a 12.5" F5.5 dob/newt. Different scopes and different focal ratios will likely yield different results. > >Greg Granville >greg@cpoclub.org Page 1 of 1 | ||||||||
