Astronomik MC Clear Glass Filter - 50 mm Square


The Astronomik MC Glass Filter shields your imaging system from dust. The scratch resistance and substrate quality of the MC filter is identical to that of all other Astronomik filters plus it has multi-coatings to prevent unwanted reflections. It does not block IR or UV and works best if your system does not contain any refracting elements.

This is the ideal filter for when it is required to keep the focal plane of your imaging system in the same location as other Astronomik filters. These latter filters will stay parfocal with your imaging system when the Astronomik MC Clear Glass Filter is used.

Made by the identical high-end process used to make all other Astronomik filters, the Astronomik MC Clear Glass Filter offers the same high quality substrate and scratch resistance. This makes the MC Clear filter parfocal with any available Astronomik filter. It can be used for protecting Schmidt-Cassegrain, Schmidt-Newtonian and Maksutov systems as well as DSLR cameras from dust without altering spectral characteristics or reducing your system's optical performance.
