The Astronomik ProPlanet 642 BP is the lastest addition to the family of Astromik ProPlanet IR-pass filters. The filter thrills because of it´s wide range of applikations 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.
What does BP stand for ?
"BP" are short for "Bandpass": 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 Astronmik 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!
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 skillfull developement with lot´s of tests we reached the goal to give you a filter which will do a perfect job to deliver amazing images.
Daylight IR-imaging:
- contrasty 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 lightpolluted skies or moonlight
- low priced filter for getting started in H-alpha imaging
- easy focussing 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.
Technical Data
- more then 96% transmission for wavelengths of 642nm to 840nm
- blocking of wavelengths between 350nm and 630nm
- Parfocal with other Astronomik filters
- Glass thickness: 1mm
- Completely resistant against high humidity, scratches and aging effects
- Diffraction limited, the filter will not reduce the optical performance of your telescope!
- Astronomik filters are delivered in a high-quality, long lasting, filter box
- Since 2008 we do ship filters with a completely new design. Any kind of halo or strange reflection is a matter of past
