Product Details

  • Astronomik 36mm ProPlanet 642 BP IR-Pass Filter
    Mounted in Low Profile Non-Threaded Cell: Astronomik's family of ProPlanet IR-pass filters welcomes a new member. The Astronomik ProPlanet 642 BP (Bandpass) has an array of possible functions including daylight IR photography, high resolution lunar and planetary imaging, and for beautiful astro-images of deep sky objects in H-Alpha regions.

    This filter provides a 200nm spectral window from 642nm to 842nm. Unlike ProPlanet 742 and 807 filters, the 642 will obstruct the longer infrared. While this gives you three filter options of imaging in the IR, many times the Astronomik ProPlanet 642 BP will be the ideal option for the highest quality image.

    Now Mounted in Low Profile Non-Threaded Cell

    Sometimes unmounted filters can be hard to handle. The smaller diameters, such as this 36mm ProPlanet filter, can be especially difficult to pick up and insert or remove from the filter wheel, and that can lead to possible damage as well as unwanted reflections from incorrectly installed filters. Astronomik has solved this problem by mounting their 31mm and 36mm filters in a low profile (3mm) non-threaded cell. O-rings, washers, or spacers are no longer required to hold the filter in place, and because the cell is only 3mm thick, it works well in all appropriately sized filter wheels. Mounted 31mm and 36mm Astronomik filters will also play nice with unmounted versions in the same carousel.

     

    Astronomik ProPlanet 642 BP Filter Highlights...

    The Astronomik ProPlanet 642 BP acts as three filters in one! This filter can be a great asset for daylight IR-imaging with a digital camera, lessening seeing effects and improving contrast when utilized for lunar and planetary imaging, and as a low cost option for those who want to begin astrophotography of deep sky objects in H-Alpha areas.

    Daylight IR-imaging:

    • High contrast images with excellent interpretation of colors
    • Clear "Wood-Effect" images
    • Longer IR hot spot eliminated
    • Short exposure times, similar to normal VIS-imaging
    • Ideal option for infrared video


    High resolution lunar and planetary imaging:
    • Short exposure times
    • Sufficient reduction of seeing effects
    • Heightened contrast
    • Longer IR blocking provides razor sharp images with no ghosting


    Deep-sky astrophotography of H-Alpha regions:
    • Peak transmission of the H-alpha line at 656nm
    • Approximately 40nm FWHM with astro-modified DSLR cameras
    • Incredible contrast despite light polluted environments or moonlight
    • Low cost filter for those interested in getting started with H-alpha imaging
    • Effortless focusing through camera display and LiveView!
