BP is an abbreviation for bandpass: The filter opens at 642nm and closes again at 842nm . It blocks the longwave infrared, unlike Astronomik's two other ProPlanet filters.

Together with the Astronomik filters ProPlanet 742 and ProPlanet 807 , you can now select three wavelength ranges for infrared images to obtain optimal images.

With the ProPlanet 642 BP you get three filters in a single product: Depending on which camera you use the filter, it is a great tool for infrared photography with a digital camera, reduces seeing and amplified in high-resolution planetary and lunar photography contrasts. It is also a low-cost H-alpha filter for entry into the DeepSky astrophotography of emission nebulae.

Infrared photography:

• High contrast images with excellent color differentiation
• Great rendering of the Wood effect
• Avoid hot spots
• Exposure times as under "normal light"
• Great for IR movie shooting!

High-resolution lunar and planetary photography:

• Short exposure times
• Effective reduction of air turbulence (Seeing)
• Reinforced contrasts in the red area
• No ghosting and sharpness by blocking the long-wave IR

Deep-Sky Astrophotography of H-alpha Mists:

• Maximum transmission of the H-alpha line at 656nm
• Enormous contrast gain under light-polluted skies or moonlight
• Affordable entry into the H-alpha photography
• Easy focusing with LiveView possible!

Further field of application: Guiding in astrophotography . The 642BP in front of your autoguider improves the quality of your tracking significantly, as it minimizes the jumps through Seeing!
