Quote:The AT paradigm is a sharp 6 element design with a 60 degree field. Small and light, it's a nice eyepiece for an inexpensive price. Good for lunar and planetary use and more enjoyable to use than a basic Plossl.1) The Paradigm, I have commented, would be my choice for a series of basic telescope eyepieces if you do not use glasses and if you do not find wider fields more enjoyable. Just remember that, in a dob, the narrower the field, the more often you have to move the scope. 2) The Hyperion is more expensive, but you do get more.3) The ES 82 series would be a good candidate if you really like the wider fields and if you don't wear glasses (they have shorter eye relief). There is an 8.8mm in the 82 degree series. The ES 82s, in 4.7-14mm, are 1.25" eyepieces.

Quote:The Baader Hyperion ....At f/5 and below, the eyepiece starts suffering from progressively larger amounts of edge-of-field astigmatism, just like the Japanese eyepiece it was originally copied from.
