The Astronomik ProPlanet 642 BP is the latest addition to the family of Astronomik ProPlanet IR-pass filters. The filter thrills because of its wide range of applications for daylight IR-Photography, high-resolution lunar and planetary imaging and for taking beautiful and deep images of H-alpha regions when used for Astrophotography.

“BP”is short for “Band-pass”: The filter gives you a 200nm spectral window from 642nm to 842nm. Contrary to the other two ProPlanet filters it blocks the longer infrared. Together with the Astronomik ProPlanet 742 and the ProPlanet 807 you can now have three choices to match your needs when imaging in the IR. The Astronomik ProPlanet 642 BP will be the right choice for the best image quite often!

Highlight of the Astronomik ProPlanet 642 BP: Three filter in one!

The Astronomik ProPlanet 642 BP will give you three filters in one single product! Depending on your camera, the Astronomik ProPlanet 642 BP is a great tool either for daylight IR-imaging with your digital camera, or it will reduce seeing effects and enhance contrast when used for lunar- and planetary imaging, and third it will be a very good and low-priced H-alpha Filter for getting started in Deep-Sky Astrophotography of H-alpha regions.
Due to our skillful development with lots of tests we reached the goal to give you a filter which will do a perfect job to deliver amazing images.

Daylight IR-imaging:

• High contrast images with a great rendition of colors
• Clear “Wood-Effect” images
• Not Hot-Spot from longer IR!
• Short exposure times, about the same as normal VIS-imaging
• perfect choice for Infrared-Videos

High-resolution Lunar and planetary imaging:

• short Exposure times
• effective reduction of Seeing
• enhanced contrast
• no ghosts and best sharpness due to blocking the longer IR

Deep-Sky Astrophotography of HII regions:

• best transmission of the H-alpha line at 656nm
• about 40nm FWHM with astro-modified DSLRs
• amazing contrast under light-polluted skies or moonlight
• low priced filter for getting started in H-alpha imaging
• easy focusing using camera display plus LiveView!

Guiding for Astrophotography:

• installing the 642BP in front of your autoguider-camera dramatically improves guiding quality, as image-motion from one frame to the next is minimized.

A Detailed description of the opportunities the Astronomik ProPlanet 642 BP will give you:

1) Daylight IR-imaging

Starting point for the development of the Astronomik ProPlanet 642 BP was infrared imaging at daylight with modified DSLR cameras.
Normal, unmodified DSLRs do have a built in Infrared-Blockin
