Optolong CLS EOS-C Clip on Filter

OPTOLONG CLS Filter Clip Built-in Filter for EOS-C Camera Planetary CCD Cameras & DSLR  

This filter is made for photography of deep sky targets in urban environments. The filter works by blocking the wavelengths or 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. Use it in traditional photography to create and experiment.

Notes: The CLS EOS -C is suitable the Camera type:7D Mark II, 80D/800D, 77D/70D/760D/750D/700D 650D/600D, 550D/500D, 400D, 100D/1100D/1200D/1300D. Notes, this Filter is not for EF-S camera Lens.

Main Features:

1. Blocks wavelengths of mercury and sodium vapour artificial lighting, vastly reducing light pollution and skyglow: you can image from within cities
2. Let critical OIII, H-Alpha and H-Beta bands through for imaging Deepsky objects
3. Contrast significantly improved, possible exposure times greatly extended
4. Inexpensive entry into the world of Deepsky Astro imaging
5. Quality aluminum construction
6. Multicoated on all surfaces
7. Light pollution reduction and contrast boosting deep sky filter for Galaxies, nebulas and clusters
8. 95% transmission of main nebula emission lines: H-beta 486.1nm, OIII 495.9nm and 500.7nm, H-alpha 656.3nm, and SII 672nm.
9. 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.
10. Fits Canon EOS digital cameras: use your existing high quality equipment and lenses
11. 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 fail to observe the warning.
