Astronomik MC Clear Glass SCT Rear Cell Filter


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.

Use this German-made Astronomik multi-coated (MC) Glass Filter if your imager's focal plane needs to remain parfocal with other Astronomik filters. Multi-coating prohibits undesirable reflections. The MC Glass Filter substitutes for a UV-IR blocker provided your system doesn't have refracting elements.

Made in Germany, the Astronomik MC Clear Filter is constructed using the exact same advanced process used to produce all other Astronomik filters. This gives the coatings on this filter the same scratch resistance, and provides the substrate with the same high level of quality, making the MC Clear Glass Filter parfocal with any other filter made by Astronomik. This filter also works to protect the front of DSLR cameras as well as Schmidt-Cassegrain, Schmidt-Newtonian, and Maksutov systems from dust without adjusting spectral characteristics, and with no reduction in the optical performance of your system.
