Astronomik Filters OIII 12nm CCD MaxFR 2" (67052)

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

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

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 robust aluminum mounts with advanced MRF coatings, ensuring reliable performance and compatibility with fast telescopes.
