I have a pair of 23mm Celestron Axioms (1.25", 70* AFOV) which have been my workhorse wide-field binoviewing eyepieces for the last 2 years. I recently upgraded to the 24mm Panoptics. The Axiom's edge correction isn't as good as the Panpotics in fast scopes (e.g. f/5) but there is little or no difference in performance in slower scopes (f/10) or when using an amplified binoviewer. Be sure to check out the reviews at Excelsis.
If you are starting out in binoviewing and looking for an excellent quality but inexpensive pair of WIDE FIELD eyepieces, these cannot be beat.
The eyepieces are in very good condition with no chips or scratches and come with winged eyeguards and bottom caps, but only one box. Price is $240.00 USD plus $10 shipping to ConUS or Canada. PayPal or International Money Order only please.
Thanks for looking!
