The SkyGlow filter is a broad-band light pollution filter. It blocks out large areas of the visible spectrum where light pollution is significant, while transmitting the nebular Hα, Hβ, and [O III] lines. This filter is not intended for continuum sources like stars or galaxies; it will reduce the sky and the target equally, providing no overall benefit.

Do not use the SkyGlow filter for CCD observing. Light pollution is brightest in the near-infrared, where the filter is relatively clear. If you need a CCD light pollution filter, we expect a short-wavelength filter will work well.
