Astronomik MC Clear Glass Filter - 31 mm


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 filter is best equipped for when it is necessary to keep your imaging system's focal plane as well as other Astronomik filters in the same location. These other Astronomik filters will remain parfocal with your imaging system when the Astronomik MC Glass Filter is employed.

Made in Germany using the exact same sophisticated process used to create all other Astronomik filters, the Astronomik MC Clear Glass Filter boasts the same scratch resistance and high quality substrate. This makes the MC Clear Filter parfocal with all other Astronomik filter models and allows it to serve as a satisfactory dust protector for the front of DSLR cameras as well as Schmidt-Cassegrain, Schmidt-Newtonian and Maksutov systems without modifying the spectral characteristics or losing any of your system's optical performance.
