This filter is suitable for non-modified Canon APS-C cameras and Canon cameras that still
have the first filter on the sensor or any filter that blocks infrared light.

This Optolong CLS filter does not block infrared light so a suitable infrared blocking filter should be used.

For Canon 7D, 7D Mark II, 80D, 77D, 70D, 60D, 50D, 40D, 800D, EOS Rebel T7i, EOS Kiss X9i, 750D, Rebel T6i, Kiss X8i, 700D, Kiss X7i, Rebel T5i, 650D, Kiss X6i, Rebel T4i, 600D, EOS Kiss X5, EOS Rebel T3i, 550D, EOS Kiss X4, EOS Rebel T2i, 500D, EOS Kiss X3, EOS Rebel T1i, 100D, EOS Rebel SL1, EOS Kiss X7, 1000D, EOS Kiss F, EOS Rebel XS, 1100D, T3, X50, 1200D, T5, X70, 1300D, T6, X80, 200D, EOS Rebel SL2, EOS Kiss X9.This filter is made for photography of deep sky targets in urban environments. The filter works by blocking the wavelengths of mercury and sodium-vapour used in urban lighting while letting the visible and the critical OIII, H-Alpha and H-Beta bands through, allowing great versatility in terms of potential objects to image.

 Note that this Filter is not for EF-S camera Lens. You need to buy a modified Canon EF-S lens or modify the lens yourself.

Main Features:

Blocks wavelengths of mercury and sodium vapour artificial lighting, vastly reducing light pollution and skyglow: you can image from within cities.
Let critical OIII, H-Alpha and H-Beta bands through for imaging Deepsky objects.
Contrast significantly improved, possible exposure times greatly extended.
Inexpensive entry into the world of Deepsky Astro imaging.
Quality aluminium construction.
Multicoated on all surfaces.

Light pollution reduction and contrast boosting deep sky filter for Galaxies, nebulae and clusters
95% transmission of main nebula emission lines: H-beta 486.1nm, OIII 495.9nm and 500.7nm, H-alpha 656.3nm, and SII 672nm.
0.1% transmission of major transmission lines of artificial light pollution: Hg (Mercury) at 435.8nm, 546.1nm, 577nm, and 578.1nm. Na (Sodium) at 598nm, 589.6nm, 615.4nm, and 616.1nm.
Fits Canon EOS digital cameras: use your existing high quality equipment and lenses.
WARNING: The filters of OPTOLONG are not designed for sun observation. DO NOT LOOK AT THE SUN WITH OPTOLONG FILTER. You would be BLIND if you did not observe the warning.
