Great eyepiece for your collection

Very easy and smooth ordering process. Came very quickly, even with covid. The eye piece it did the ip's is great regarding the eye relief. Would highly recommend this piece.

Outstanding!

Oh wow!!! It’s so wide I can still use it to do the alignments. But yes views are beautiful.

It's my go to lense for showing objects in the sky.

The wide angle lets you see the moon close up and fits the entire moon in the viewer. It's my go to lense for showing objects in the sky.

Best binoview ever in Oberwerk BT-100/45

Scanning starfields across Milky Way yields gazillions of pinpoints of starlight! Serves up clusters, nebulae galore! Observing Saturn yields planetary banding, and gap between planet and rings! Pros: great brightness, contrast and resolution Cons: pricey...

Amazing - almost TOO good!

I use it with permanent f/4.5 29-inch Dob, Paracorr and Dioptrx. That's a lot of glass! The field is SO wide that although can see it all looking straight in, must move head to concentrate on edges. Measured throughputs in photometric labs: R=94.7%, G=93.7%, B=91.7% attest to great MARC coatings throughout. Wonderful on remote galaxies. Get one 13mm for your favorite higher mag - full set would be overkill. Use Naglers for other EFLs. Best on fast Dobs, overkill on slow scopes. Buffalo club visited and were all +++ impressed.

More Ethos magic from Tele Vue!

I have used this 6mm eyepiece coupled with a small barlow on a TV-85 to get wonderfully close, sharp views of the moon, planets and other deep sky objects. As with other Ethos pieces, the field of view gives a whole new meaning to the phrase "space walk" - you get the feeling you're looking out a space craft. [...]

EXCELLENT- best view and contrast!!

This is great in both my TV 85 and 4" Genesis. Yes, it is a little expensive but the stunning views will make you forget. Sell a few of your other eyepieces to afford it if you have to. You'll be glad you did.

Stunning views - Tack-sharp across field

I have had the most stunning views of the Moon that I have EVER seen through this eyepiece. The Veil Nebula (with an O-III filter) was breathtaking! I am getting rid of other eyepieces because this is mostly what I use now.
