    Default Wide FOV eyepieces



    I understand that an eyepiece with a large apparent FOV (100 deg)can give you more FOV in your scope, but is $400 the best price? I can get a small refactor scope for less than that.

    Some people can not enjoy driving anything less than a Porsche car, the others are perfectly happy with Toyota Camry versatility. I would not use an eyepiece that will keep me looking after it all the night - instead of looking in the sky. My curiosity however gets the best of me, I'd like a peek through it. Nothing more, nothing less.

    It's like anything, just depends on how much it is worth to you. One way to get a feel for it is to attend a star party and look through EPs of varying AFOV, such as 68, 82 and 100. See what is comfortable for you. Some like the experience of rolling their eye around a large AFOV, others don't, and stick with EPs with less AFOV.

    The $400 you quoted is for the ES 100 20mm I presume. The same series also has a 14mm for $300 and a 9mm for $250. Zhumell also markets a 100 deg 16mm EP for $210. But there is also the 82 deg series from ES as well, which is what I am looking at presently. They are less expensive and certainly give you a large AFOV as well.

    EPs are a very personal choice. You have to find out what is important to you, what works for you, and how much you are willing to spend.

    You pay for the last 10% of the field of view to be flat and without coma. Most of us are happy if 90%+ of the field of view is sharp and the last 5-10% is not so sharp.
