The 2-group 4- element Plossl series eyepieces offer flat and clear images with good color correction. The NPL20, NPL25, NPL30 and NPL40 eyepieces feature a twist-up eye cup.

A top notch Symetrical-Plossl 15mm EyepiecePros: Cons: Comments:
I have found this eyepiece to be sharp, neat around the field edge with not edge darkening. It had neutral grey tones, which I like, and good contrast. The eyepiece is made well with attention to detail. The lens covers slip on straight with no hassles and stay in place until deliberately removed. No rubber eye guard to flip up and down until it wears out.

Really happy with eyepiecePros:
Quality LensesCons: Comments:
This lense is a big improvement over my "came with the telescope" eyepiece. Best price and free shipping to boot. Ordered this one shortly after receiving the 10mm version. Have been very happy with the items ordered from Agena. Everything has arrived quickly and no problems.
