Lumicon 2" Comet Filter

The Lumicon 2" Comet Filter, a narrow (25 nm) band-pass filter, isolates the 501 nm OIII line and both C2 lines at 511 nm and 514 nm. The high contrast of the filter reveals the delicate ionized tail of gaseous comets, allowing you to see their full extent. The Comet Filter also helps you to better distinguish gaseous comets from dusty comets, which normally show little contrast gain. The Lumicon Comet Filter is designed to enhance the cyanogen (CN) wavelength found in comet tails. This filter is made to fit into standard 2" eyepieces which have filter threads.

To ensure that your Lumicon filter remains the World's Best, the strictest quality control standards are employed throughout the production process. Each Lumicon Comet Filter is individually inspected and proudly inscribed with the percentage of light transmittance of the primary emission lines at 501, 511 and 514 nm.

Sebastian ★★★★★

First night out with this filter and the difference on comets is striking—the C2 lines at 511 and 514 nm really make the coma pop against a dark sky. I was expecting a subtle change, but the 25nm band-pass cuts through light pollution like nothing else. Already my go-to for lunar imaging too.

Scarlett ★★★★★

I was initially skeptical about how much difference it would make on my 8-inch Dob, but the first night I used it on the Swan Nebula the C2 lines at 511 nm and 514 nm really made the structure pop. That narrow 25 nm band-pass cuts through light pollution like nothing else I've tried, and I'm even pi

Ellie M. ★★★★★

I've had this 2" filter for a few weeks now, and the 25 nm band-pass on the OIII line really makes the comet's structure pop without washing out the surrounding stars. It threaded onto my focuser smoothly and feels solid.
