The Astronomik ProPlanet 642 BP is the lastest addition to the family of Astronomik ProPlanet IR-pass filters. The filter thrills because of it´s wide range of applications for daylight IR-Photography, high-resolution lunar and planetary imaging and for taking beautifull and deep images of H-alpha regions when used for Astrophotography. The "BP" is short for "Bandpass": This filter gives you a 200nm spectral window from 642nm to 842nm. Unlike the other two ProPlanet filters it blocks the longer infrared. Together with the Astronmik ProPlanet 742 and the ProPlanet 807 you now have three choices to match your needs when imaging in the IR.

Highlights of the Astronomik ProPlanet 642 BP:

Three filters in one! 1- Depending on your camera, the Astronomik ProPlanet 642 BP is a great tool either for daylight IR-imaging with your digital camera. 2- It will reduce seeing effects and enhance contrast when used for lunar and planetary imaging, and 3) It is a very good and low-priced H-alpha Filter for getting started in Deep-Sky Astrophotograph of H-alpha regions.
