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
