Lumicon 2" Minus Violet Filter

Use Lumicon's 2" Minus Violet Filter to improve astrophotography using any lens that you choose. The Minus Violet filter passes the maximum amount of visible light, including the full blue, green, yellow, and red portions of the spectrum. It absorbs violet and ultraviolet light below 420 nm and thus eliminates blue halos around bright stars in color photography. In photography, it eliminates bloated and swollen star images caused by violet and ultraviolet light, which telephoto lenses cannot focus exactly, due to chromatic aberration.

Designed using specially made colored glass that is optically flat, the Minus Violet Filter features anti-reflection coatings on all optical surfaces. Be sure to use this filter for all telephoto lenses to achieve pinpoint star images.

Customer Reviews (4.6 / 5 · 5 reviews)

Riley ★★★★★

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.

Olivia ★★★★★

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.

Ruby ★★★★★

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.
