APM Eyepiece UW 30 mm 80°
The APM Ultrawide eyepiece employs a 5-element, non-Erfle design. APM’s Ultra wide eye piece uses fully multi-coated high index glass, providing the highest transmission of light; this high light transmission is apparent when you push your telescope to its magnitude limit. APM’s Ultrawide eyepiece has 22mm of eye relief and no “kidney bean effect”. Ghost images as well are completely absent.
When using with Lumicon Nebula filters for viewing planetary nebulas, you will find you are not at a disadvantage against other much more expensive eyepiece models. The lightweight design of the eyepiece – weighing in at just 1.2 pounds – makes it very comfortable even with Dobsonian style telescopes that have critical balancing problems.
