(SOLD!) BW-Optik Ultrawide 30mm, 80° FOV, $80. End caps, double-sided bolt case, original box. Untouched optics.

Not quite as flat of a field as I'd like to see, but a very nice eyepiece for the price!! Great 22mm eye relief.

$80 plus $3.95 shipping. PayPal preferred. Will ship 2-3 Priority Mail shipping. See specs below.

This eyepiece provides low power deep sky observing for large nebulae, galaxies and star fields with highest contrast and highest transmission. The edge performance is not as good as TeleVue Naglers, but it still has good field correction. Recommed for f/6 and longer focal length telescopes.
The BW-Optik Ultrawide employs 5-element design (not Erfle). Ultrawide uses fully multicoated high index glasses producing high transmission. This high light transmission is visible when you push your telescope to its magnitude limit. The Ultrawide has 22mm eye relief and no kidney bean effect. Ghost images are totally absent.
Using Lumicon Nebula filters on planetary nebulaes you will not be at a disadvantage against other much more expensive models. The lightweight design weighing just 1.2 pound makes it very comfortable when using Dobsonians with critical balancing issues.
