The L-Pro filter from Optolong is a multi-bandpass filter that works well for photographic use with your Canon Full Frame. Better color balance is achieved by maximizing the transmission band, allowing you to produce images of broadband emission objects with 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 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.
