Leica HC Plan S 10x/25

[Highburymark]

Last year I acquired a pair of Leica microscope eyepieces - HC Plan S 10x/22 M (507806). Basically this translates to a 25mm eyepiece, with a 22mm field stop. HC Plan S are Leica’s best range, and they really shine in an astronomical binoviewer. The 22s can be tracked down on ebay for around £200-250 for a mint used pair. I believe they are over three times that price new. Although you have to add 1.7mm to the barrel (I just use paper and tape) to fit a 1.25” binoviewer, it is worth it. They are the sharpest and cleanest 25mm eyepieces I’ve ever used. 
This week I received the wider model - the HC Plan S 10x/25 (507808). So far I’ve only used them for solar Ha and white light, but they are exquisite. I know there are a few people interested in these eyepieces on SGL, so thought I’d share a few pics.
