Astronomik CLS Light Pollution CANON EOS Clip Filter This is brand new and as the photos try to show, remained sealed until now.It has been carefully removed for the photos but otherwise is as we received it – new.
A little bit about this filter:The Astronomik CLS is a budget filter for visual observation, Black & White photography and CCD photographs of nebulae, galaxies and star clusters with astronomical instruments of any size.The Astronomik CLS blocks the light of the spectral lines of mercury and sodium-vapor lamps and lets the largest part of the visible light and H-alpha emissions pass. All the important emission lines, as well as the spectral region that the very well dark adapted eye can see, can pass through the filter. Suitability
Visual observation (dark skies): Good, to reduce light pollution by mercury-vapour lamps (streetlight)
Visual observation (urban skies): Good, an UHC-E or UHC filter is more suitable
Film photography: Very good, colour balance is near perfect
CCD photography: Good, when used with an additional IR-block-filter
DSLR photography (original): Good, colour balance shifted but contrast enhanced
DSLR photography (astro modified): Very good, colour balance is near perfect
DSLR photography (MC modified): Good, when used with an additional IR-block-filter
Webcam / Video (Planets): Unsuitable
Webcam / Video (Deep Sky): Very good, if light pollution is a big problem.
