This review of the Sterling eyepieces strongly supports what I've contended for years- that there are quality eyepieces out there that are difficult to discriminate from much more expensive ones at 1/3 or 1/4 the price. Tim

I was admiring the wonderful photos of the Moon by Michael Downs when I ran across this at the end of his article about the Sterlings:

"Keep in mind that I simply hand held a point and shoot camera up to the eyepiece."

Wow. The color and contrast of the images are fantastic for such a simple method! Nice work, Michael.

I purchased the Sterling Plossl based on the reviews at CN! It's really is a great value.

Thanks for the wonderful review!!!

Great review.

I would also be really curious how the Sterlings stack up against cheaper Plossls, like the $20 Owl ones.

When I first received the sterlings I had a couple of lower end plossls on hand,a 26mm (meade 4000 clone) and a 20mm. There simply was no comparison.Much better definition and contrast levels left those two in the dirt.Really.I have not had an owl eyepiece in some time and cannot comment on such other to say unless they have improved thier coatings significantly in the past few years I don't think they could really compare.Thank you for your comments and interest!

I only have one Owl and it does not overlap in focal length with my Sterlings, but it has a somewhat narrower AFOV. I like the Sterlings much better in terms of crispness and the quality of the views. Not a fair comparison, though, since I don't have the two models in the same focal length.

I just went out last night and made a direct comparison between a 20 mm sterling plossl and a 20 mm televue plossl. I was looking at the orion nebula and the sharpness of the image was noticeably better(not by a huge margin) in the tv. My brother was there and he also agreed. I saw the stars as being sharper pinpoints in the nebula. Another very very annoying thing about the sterling was that it has no eyecup and it has a very large exposed lense near your eye. This means your eyeball is practically on the lense unless you hover your face back from the lense without touching the eyepiece. Basically if you let your face touch the eyepiece your eyelashes will touch the lense and deposit eyelash grease on the lense. I saw the grease after my brother and i used the eyepiece. So cut off your eyelashes before using this eyepiece, dont blink so your eyelashes will stay away from the glass, or don't buy this eyepiece. The optical quality of the sterling is not far off the tv, but it needs an eye cup. I could not find any available on the internet. Edmund optics has some, but they are not properly designed to distance your eye from the sterling. Conclusion: the sterling has a bit of a *BLEEP* design, and the eyelash grease will degrade your view. I say go for the tv. As far as tv eyepieces go this one is a bargain at $120. It will give you the quality of picture that a $330 nagler will give you but just a little narrower. Plossls rock!
