Astronomik Luminance Filter - 50 mm Round Mounted

Mounted in a round 50 mm cell, this Astronomik Luminance Filter only permits the passage of light from the part of the spectrum that is visible to the human eye, while the remainder of the spectrum in the UV and IR is blocked. Problems imagers have to deal with in the UV and IR areas of the spectrum for any type of digital photography are eliminated. Compatible with systems featuring focal ratios between f/0.5 and f/50. 99%+ transmssion is typical.

This filter can be used to protect Schmidt-Cassegrain, Schmidt-Newtonian, and Maksutov telescope systems, as well as the front of DSLR cameras, from dust. In addition, it also functions as an alternative to the IR blocking filter for cameras with high sensitivity at short wavelengths. For telescope systems that contain any refracting elements, the Astronomik 50 mm Luminance Filter can substitute for the MC Clear Filter.
