Lumicon Band Comet 1.25" filter

The Lumicon Comet filter, A narrow band-pass filter system (25nm), isolates the 501nm OIII LINE and both Cyanogen LINEs RK 511nm and 514nm. The high contrast gain OF the filters reveals the delicate ionized tail OF gaseous comets, allowing you ton lake their full extent. The Comet filter thus helps you tons better distinguish gaseous comets from dusty comets which normally show little contrast gain.
