Pentax XL 21mm
Wonderful wide-field eyepiece, 20mm eye relief and 65-degree AFOV.
It's been my favourite eyepiece for the last few years, but now that I have a Mak-Cass with focal length of 2700mm, I'm looking for a Nagler to go a bit wider.
Very good condition. Have the bottom end cap but not the top one.
Price-wise I'm looking around $170 ono, and am open to offers involving a trade for a Nagler in the 12mm to 16mm range.
Picture to follow.
Thanks for looking.
