Astronomik Filters OIII 6nm CCD MaxFR 31mm (67072)

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

This series includes narrowband filters for the three key emission lines in astrophotography: OIII, H-alpha, and SII. With a full width at half maximum (FWHM) of 12nm or 6nm, these filters allow precise isolation of specific wavelengths, enhancing contrast and reducing interference from unwanted light sources.

Applications and Features

The MaxFR filters are ideal for astrophotography, particularly for capturing nebulae and galaxies. They are highly effective in reducing light pollution but are not intended for visual observation or imaging twin stars, the Moon, or planets. As part of the MaxFR line, these filters combine durable aluminum mounts with advanced MRF coatings to ensure reliable performance. Their precision and compatibility make them an excellent choice for astrophotographers using fast telescopes.
