| Filters are 30mm diameter, and mounting is 39mm dia. Looks like they were made to snap in place as there is a ring on the back side that sticks out 4mm and is 33mm diameter. Too big to be used as is in your 1-1/4" telescope eyepieces but maybe you can get creative with them. The Neutral Density one is quite dark and may make a decent moon filter. We believe these were made for some military application. |
