Astronomik Filters OIII 12nm CCD MaxFR Clip Canon EOS APS-C (67053)

The MaxFR series is specifically optimized for astrophotography with very fast telescopes, such as the Celestron RASA systems or Takahashi's Epsilon astrographs. These filters are designed to deliver exceptional performance with fast optical systems, ensuring detailed and high-contrast imaging of deep-sky objects.

This series includes narrowband filters for the three critical emission lines in astrophotography: OIII, H-alpha, and SII. Each filter features a full width at half maximum (FWHM) of 12nm or 6nm, enabling precise isolation of specific wavelengths to enhance image clarity and contrast. With a high transmission rate of 85%, these filters maximize light capture while reducing interference from unwanted wavelengths.

Please note that while the MaxFR clip-filters are compatible with Canon EF lenses and other third-party camera lenses (such as Sigma, Tamron, Tokina, Walimex), they cannot be used with Canon EF-S lenses.

Applications and Features

The MaxFR filters are ideal for astrophotography, particularly for capturing nebulae and other deep-sky objects. They are specifically designed for photographic use and are not intended for visual observation. As part of the MaxFR line, these filters combine durable aluminum mounts with advanced MRF coatings, ensuring reliable performance. Their compatibility with Canon EOS cameras and various camera lenses makes them versatile tools for astrophotographers using fast telescopes.
