COMPLETED - SOLD - Pentax XW 5mm Eyepiece

Pentax XW 5mm Eyepiece

In perfect as new condition. Bought from FLO in June 2020. In original box.

Great eyepiece but want a different focal length.

This short focal length eyepiece is particularly popular as it delivers more-or-less the maximum useful magnification from an 8-inch or 10-inch f/10 Schmidt-Cassegrain telescope.

Odly enough as I was updating the listing someone else sent a message saying they would have it. Just missed out  by a minute. Feel sorry for them. 🙁
