Astronomik SCT Rear Cell IR Blocking Filter

The Astronomik IR Blocking Filter is best suited for when sensors with low sensitivity in the UV area of the spectrum, such as with Webcams, Meade DSI and LPI, and most video systems, are in play. Place this filter ahead of your DSLR camera to completely eliminate common IR induced problems like bright halos surrounding objects as well as general image softness.

Most manufacturers would consider the Astronomik IR Blocking Filter to be a UV-IR blocker when taking its transmission data compared with data from outside sources. However, what Astronomik determines is a "UV-IR blocker" tops any UV-IR blocker on the market from any manufacturer in the world!

Enhanced for systems that have focal ratios ranging from f/0.5 to f/50, this SC Rear Cell IR Blocking Filter has a typical transmission over 99%. It can be used in place of the UV-IR Blocker for protecting your DSLR camera or Schmidt-Cassegrain, Schmidt-Newtonian, or Maksutov telescopes from dust; or for use with cameras that have low sensitivity at short wavelengths. It can also be used as a substitute for the MC Clear filter provided your system does not contain any refracting elements.
