Univesity Optics 25mm MK 70.
An incredible eyepience. Here's what the review in Cloudy Nights says about it:
If you are a perfectionist, this is the eyepiece for you. It gets completely out of your way. It's as good optically as the 22mm Nagler Type 4 and you don't have to crowd the eyelens to see the full Field of View."
