APM Eyepiece UW 30 mm 80°


The APM Ultrawide employs a 5-element, non-Erfle design. The Ultrawide uses fully multicoated high index glass providing the highest transmission. This high light transmission is visible when you push your telescope to its magnitude limit. The Ultrawide has 22mm of eye relief and no kidney bean effect. Ghost images are totally absent.

Using Lumicon Nebula filters on planetary nebulas you will not be at a disadvantage against other much more expensive models. The lightweight design - weighing just 1.2 pounds - makes it very comfortable when using Dobsonian's with critical balancing problems, such as the Portaball 12.5".
