Eye relief
I have worn spectacles for most of my life and of course the term "eye relief" is important to me.
Some time ago I bought a Tele Vue 17.3mm Delos eyepiece and it is the most comfortable eyepiece to use that I have in my set. It has an apparent field of view of 72 degrees.
Some eyepieces with a metal eye-stop will scratch ones spectacles while trying to observe the entire field: big problem!
The Delos design is a compromise between an eyepiece with a super wide field and a narrower field eyepiece with a large eye relief.
