Orion 10.5mm Megavista in excellent condition. It has a 67 degreee field in a 1 1/4" housing. It's great eyepiece but don't take my word for it, you can read about it on the Cloudynights website. Here is an excerpt:
"the Megavista is unique in having both an excellent level of sharpness, with a superlatively well corrected FOV that does not degrade towards the edges...the 10.5mm Megavista seems to be one of the best for excellence in wide full field performance"
