    Marumi Magnetic Slim StarScape/Adp.

    The Marumi Magnetic Slim StarScape/Adp. functions as a magnetic adapter as well as a light pollution cut filter, screwing into your lens thread as a magnetic base. 

    • Enables astrophotography to bring well-controlled color balance by suppressing unwanted color shifts to an orangish or yellowish picture.
    • To secure the exposure that is indispensable for starscape photography, only 1/4 stop equivalent to 1.2x Filter factor is realized.
    • Easy-to-maintain coating embedded, twelve layers in total on both sides;
    • Water-/Oil repellent coating sheds water off simply also by the air blower. Nuisances such as sweat, skin crème, lotion, fingerprint, or compounded grease stains will be wiped off.
    • Anti-reflection coating sustains a low reflection.
    • Made in Japan

    [Attention!] The Magnetic Slim StarScape/Adp. is a component included in the Magnetic Slim StarScape Kit and is not sold separately as an individual product. 



    What do we use a StarScape Filter for?
    When and on which occasion do we need to use Marumi StarScape filter?

    StarScape filter is essential for photographers aiming to capture the true beauty of the night sky in areas affected by light pollution.
    It is particularly useful for astrophotography, nightscape photography, time-lapse shooting like the above short film, and photographing phenomena like the Aurora Borealis.
    it reduces the need for extensive post-processing to correct light pollution, saving time and effort. 

    Marumi offers three different filter construction for StarScape.
    - StarScape for Screw-in filter
    - StarScape for M100, Square fiter
    - StarScape for Magnetic Slim

    Optical Properties of StarScape

    The StarScape filter selectively absorbs specific wavelengths of strong light emitted by artificial urban light sources, which are the main cause of light pollution, while allowing the wavelengths from celestial bodies to pass through. This effectively cuts light pollution without compromising the colors of celestial objects.

    Sources of Light Pollution

    Light pollution refers to artificial light sources such as:

    • Mercury lamps (435.8, 546.1, 577.0, and 579.1 nm)
    • Sodium lamps (589 nm)
    • LEDs (approx. 470 nm)
    • Fluorescent lamps
    • Automobile headlights that brighten the night sky and make it difficult to see stars

    The transmission curve above shows a decrease in transmittance for specific visible light wavelengths (400-700nm), such as mercury lamps (435.8, 546.1, 577.0, and 579.1 nm), sodium lamps (589 nm), and LEDs (approx. 470 nm). This indicates that these artificial light sources emit harmful orange and yellow light, which can interfere with astronomical observations and contribute to light pollution, making it difficult to see cold color stars in the night sky.

    What is "Light Pollution"?

    Light pollution refers to artificial light sources such as;
    -
    mercury lamps,
    - sodium lamps,
    - LEDs,
    - fluorescent lamps,
    - or Automobile headlights that brighten the night sky and make it difficult to see stars.

    In modern inhabited areas, it is hard to see the Milky Way in urban cities, and when you take a picture, the night skyscape sometimes turns obviously yellowish. This color shift phenomenon is caused by, so to say, "Light Pollution".
    This color shift makes the starscape-/nightscape photograph enthusiasts very annoyed.

    How Marumi StarScape eliminates Light pollution?

    By kneading a component that absorbs unwanted light into the glass, the color shift phenomenon will be suppressed, turning the overall image natural bluish.
    In addition, no matter which white balance is selected, there is no extreme color shift.

    The brightness, which is a significant element for starscape photography, can be sufficiently secured at an exposure multiplier 1.2 (about 1/4 stop).

     

    The StarScape filter is also available in the M100 Square Filter System, and Screw-in type of filter.
