Crystalview 2-Inch Moon and Contrast Filter
Crystalview 2" Moon and SkyGlow Filter
During daytime observations this filter removes the violet glow at the edges of observed objects and also increases the contrast of refractors.
When used for astronomical observations, much more fine details can be observed on the surface of the planets and the Moon.
It also has a similar effect against light pollution as Baader's Neodymium and Skyglow filter.
