    Optolong L-Pro Broadband Clip Filter for Canon EOS Full Frame Cameras

    Ready your Canon EOS Full Frame camera for a wide range of viewing conditions with this L-Pro filter by Optolong. This is a multi-bandpass filter, creating a range of astro-imaging capabilities for your camera. Achieves optimal color balance by maximizing the transmission band. This will enable you to produce images of broadband emission objects with a nominal color cast.

    By reducing the transmission of artificial and natural light pollution, including neutral oxygen (skyglow) as well as light given off from mercury and sodium vapor lamps, the background sky will become darker, allowing the good stuff to shine through. High transmission of main nebulae emission lines at OIII, H-Beta, NII, H-alpha, and SII, when combined with the precision off-band blocking of contrast-killing light pollution, makes this filter perfect for most emission nebulae, reflection nebula, and dark nebulae.

    The Optolong EOS Full Frame Clip L-Pro Filter is made with Schott glass that has been multi-coated with an ion-assisted deposition technology to ensure scratch resistance and stability on the central wavelength, or CWL. The filter cell is made of lightweight, strong metal and is CNC machined, sand-blasted, black anodized, and then laser engraved.

     

    Using a Clip Filter on your Canon Full Frame Camera

    • The Optolong EOS FF Clip filter can be inserted without tools; just use your fingers to insert or remove the filter. Once inserted correctly, it cannot unintentionally fall out.
    • No changes to the housing of Canon EOS DSLR are required. All lens functions will work with the Clip installed, including focus, screen, and image stabilization,
    • The Optolong clip filter prevents dust from settling on the sensor during long exposures.
    • The EOS FF clip filters are compatible with EOS Full Frame series cameras, such as the 1D X, 5D, and 6D. If you have a standard APS-C EOS camera, Optolong offers clip filters for these cameras as well.
    • Optolong Clip Filters do not function with the Canon EF-S series lenses. These lenses invade the space inside the camera body that would normally be taken up by the clip filter.
    • To use EOS/T2 and 2” adapters to attach your camera to a telescope you’ll need to insert the Clip-Filter first and then install the desired lens adapters.

     

    Quality Filter Materials:

    • Schott B260 substrate material from Germany, 1.0mm thick
    • CNC machined and black anodized aero-metal filter cell that is ultra-thin to provide largest clear aperture; Laser-engraved to prevent fading
    • Multiple layers of anti-reflection non-cementing coatings applied via electron-beam gun evaporation with Ion-assisted deposition

     

    Optolong Filter Manufacturing Processes and Parameters

    • Filter substrate is fine-optically polished to 1/4 wave and <30 parallelism over both surfaces
    • Surface quality, according to MIL-O-13830, is 60/40
    • High transmission at major nebula emission lines (i.e. H-alpha 656nm, OIII 496nm and 500nm, SII 672nm and H-beta 486nm)
    • Precision off-band blocking, specifically the major emission lines of artificial light pollution (i.e. Na 589nm, Hg 435nm and 578nm)
    • High-value transmission of pass-band and optical density of off-band is assured through Optolong’s planetary rotation system, a homogeneous and precise coating procedure
    • Each filter comes with a plastic case with high-pressure EVA case lining
