Kenko "HF" astronomy filter, 22mm threads for .965" eyepieces, made in Japan. Unfortunately we haven't been able to identify exactly what this filter does though from the medium blue appearance of reflected white light when viewing through it with the naked eye suggests it might be for deep sky use. Anyone know?
Note this is for the older, smaller .965" astronomy eyepieces, not the current 1.25" size.
