Lumicon 1.25" Comet Filter
The Lumicon 1.25" 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 1.25" 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.
