Darkness Matters

Eyepiece is of excellent quality. It arrived quickly and was well packaged. Only issue is when using it with my Dobsonian 8” reflector and the exit pupil being so small as it is can be very finicky with eye position. I’m not returning it because I believe with more practice it will become easier to use - hence only using it twice so far. The views are outstanding when I’m able to use it correctly and am pleased to have acquired it. - Eric -
