Astronomik Filters SII 12nm CCD MaxFR Clip Canon EOS R XL (67137)

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

It is important to note that Clip-Filters are compatible with most camera lenses, including Canon EF lenses and third-party options like Sigma, Tamron, Tokina, and Walimex. However, they are not compatible with Canon EF-S lenses.
