Lumicon 2" Minus Violet Filter - LF3125

Finally, a filter that actually kills the violet halos around bright stars without dimming the whole image too much. Slid right into my 2" focuser and made my last lunar session look noticeably cleaner.

Took this out on a clear night with my refractor and the difference in color fringing was immediate—the view snapped into focus with way less purple haloing around bright stars. It threads into the 2" diagonal without any hassle, and the light transmission feels like it barely cuts anything at all.

Switched from a cheaper filter and the difference in star sharpness is immediately obvious—the violet cutoff actually works. It threaded smoothly onto my 2" eyepiece and darkens the sky just enough for clear lunar shots without losing detail.
