This is an outstanding eyepiece. One of my favorites. I'm only selling it because I'm trying to stay with the Nagler line. Probably the best views of Saturn and Jupiter I've ever had were with this eyepiece. The 65 degree fov is great.
The field is flat even in a faster scope such as my f5. In my 10 inch 1255mm dob it yields a magnification of 179x which is a real sweet spot even under less than perfect seeing conditions.
The eye relief is a generous 20mm with a twist screw adjustable eye cup. Unlike a Radian, when you adjust the eyecup it doesn't slip back down.
The XL line is no longer in production. The XW line which replaces it sells at $339.
The barrel is in excellent condition and the eyepiece is generally cosmetically excellent. The glass is mint. I take pride in taking great care of my equipment. I have a box, boltcase and caps.
$200 shipped insured to the CONUS. Paypal, money order or cashier check. It's packed up and ready to ship to a good home.
Thanks for looking.
