Lumicon 2 Inch Comet Filter
Lumicon 2 Inch Comet Filter is a narrow band-pass filter (25nm), which isolates the 501nm OIII line and both C2 lines at 511nm and 514nm.
The high contrast of the filter reveals the delicate ionized tail of gaseous comets for optimal viewing. The Comet Filter also helps better distinguish gaseous comets from dusty comets, which normally show little contrast gain.
Lumicon filter remains the world’s best and strictest quality control standards are employed throughout the production process. Each Lumicon Comet Filter is individually inspected and scanned with the percentage of light transmittance of the primary emission lines at 501, 511 & 514nm.
