Improving your visibility of deep sky objects during nighttime, the CLS Nebula Filter from Explore Scientific increases the contrast between the night sky and astronomical objects. Ideal for visual observation and astrophotography applications under light-polluted skies, this filter features a wider transmission curve than a UHC filter and helps to brighten the appearance of stars and other phenomena by reducing light pollution wavelengths. It is designed for 1.25"-diameter telescope eyepieces and viewing accessories.
