Skywatcher Hydrogen Alpha CCD Filter 1.25"

This long-pass filter limits transmission of light with wavelengths longer than 650nm. Whilst suppressing all other polluting lights, the filter allows you to observe emission nebulae with greatly enhanced contrast. Ideal for observing emission nebulae or objects that emit in the H-alpha region.

Suitable only for CCD photography.
