Lumicon 1.25 Inch Comet Filter
LF3070

$100.00

Lumicon 1.25 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.

Lumicon 2 Inch SCT Rear Cell Comet Filter
LF3080

$200.00

Lumicon 2 Inch SCT Rear Cell Comet Filter is a narrow band-pass filter (25nm), which isolates the 501nm OIII line and both C2 lines at 511nm and 514nm. The filter cell threads onto a Schmidt-Cassegrain Telescope rear-cell, and presents male SCT threads for accessory attachment. The filter cell allows ease of eyepiece changes without threading/unthreading the filter, and is also easier to change-out than the standard 2″ filter cell with gloves on, for cold-weather observing.
