The MaxFR series of filters is optimized for astrophotography with very fast telescopes, such as the Celestron RASA telescopes or Takahashi's Epsilon astrographs. These filters are specifically designed to capture the three key emission lines in astrophotography: OIII, H-alpha, and SII, with a full width at half maximum (FWHM) of 12nm or 6nm.

This multicoated (MC) glass filter functions as a dust protector or to maintain a parfocal setup with other Astronomik filters. It ensures that the focal plane of your imaging system remains consistent when switching between Astronomik filters. The advanced multicoating minimizes unwanted reflections and does not block IR or UV light.
