Sky-Watcher H-Alpha 12nm Long Pass Filter 1.25"

H-ALPHA 12NM LONG PASS FILTER 1.25"
LONG PASS FOR CCD PHOTOGRAPHY

This long-pass filter limits the transmission of light from wavelengths longer than 650nm. While blocking all other light pollution, this filter allows the observation of emission nebulae with significantly increased contrast. It is therefore ideal for emission mists and objects that radiate in the H-alpha range. It only makes sense for CCD photography.
