BAADER NEUTRAL DENSITY FILTER 1.25" Transmission:OD 3.0 T=0.1% The Chroma LRGB filter setBaader 1. 25" Neutral Density filters are available in a range of optical densities to reduce the brightness of objects such as the Moon or the Sun (only with additional energy rejection filter), between OD 0. 6 which lets through 25% of light all the way to OD 3. 0, letting through only 0. 1% of light. Warning: Polarizer and neutral density filters need additional filtering (for example, Baader Herschel Prism or Baader Astro Solar Safety Film) before
