Our photos show the eyepiece with the twist up feature eyecup up and also down. A great feature for those who use eyeglasses. No Field Curvature or Pincushion effect. Air Spaced Blackened lens edges Fully broadband multi-coating All models are Parfocal Smooth twist-up eyecup I am impressed at just how "clean" the image is, with the background sky being black right up to the planet. With my 102mm/F7.75 doublet apochromat, bright stars show up as lovely jewels. Orange, white, or bluish white, all bright stars had nice saturated colors. Airy discs were perfectly round with no comet tails. I also saw an improvement in edge definition on f/6 scopes or longer. David Elosser, Cloudynights Reviews |
