Hello, this is my follow up review. After having this eyepiece for a while I have had the chance to compare it back to back with my televise Delites. I like the twist up cap better on the Pentax, I enjoy the larger glass area (afoot) and it has its own distinct look. I recommend this highly and I did decide to purchase the venerable 10 mm.

Very comfortable eyepiece

This twist-up eyecup design is the best I've used. The optics are excellent as expected.
