TeleVue 31mm Nagler Type 5

Remarkable eyepiece!

A truly extraordinary eyepiece, definitely worth the price. Excellent sharpness and contrast, comfortable eye relief without glasses. Maintains sharpness nearly to edge in an f5.4 reflector and is even better in an f6.6 refractor. Its big and heavy and will probably require you to rebalance your scope, but those are minor problems. The views with this eyepiece remind you why you got into astronomy!

Outstanding for deep sky

Very happy with this eyepiece. Its my favorite for examining discrete deep sky objects, with excellent contrast and sharpness to the edge of the field. I find that the Instajust eyeguard allows for individualized framing of the view and is easy to use, although there is some range of opinion about it. Very comfortable eye relief. Highly recommended!

Fine eyepiece

Has excellent on-axis sharpness and superb contrast. In an f5.4 reflector and f6.6 refractor, edge sharpness was not as good as a 12.5mm Celestron Ultima. Edge sharpness is not a problem, I hear, in longer f-ratio scopes - nor is it a problem with the 5mm and 7.5mm Tak LE.

Fine eyepiece

Like the 12.5mm, has excellent on-axis sharpness and superb contrast. In an f5.4 reflector and f6.6 refractor, edge sharpness was not as good as a similar focal length Celestron Ultima. Edge sharpness is not a problem, I hear, in longer f-ratio scopes.

Excellent eyepiece

Has excellent on-axis and edge sharpness, with superb contrast. A great planetary eyepiece, and fine for smaller clusters and nebulae.

Excellent eyepiece

Has excellent on-axis and edge sharpness even with low f-ratio scopes, with superb contrast. Comfortable eye relief (10mm) for this focal length. A great planetary eyepiece, and fine for smaller clusters and nebulae.
