⚠️ Merci de bien choisir votre version de filtre dans le menu déroulant sous la mini description |
The CLS CCD is suitable under light polluted skies for ASTRO defiltered then refiltered DSLR cameras. The filter improves the contrast between all deep sky objects and the background.
The CLS-CCD filter improves the contrast between astronomical objects and the background. Due to the wider transmission curve compared to UHC filters, more light will pass the filter. The stars will be less dim. This filter has been optimized to block as much stray light as possible and simultaneously provide the best performance for “useful” light. A good filter for black-and-white photography with DSLR, CCD, and film, as well as for observing deep-sky objects with telescopes or camera lenses of all f/2 apertures and above.
⚠️ CLS or CLS-CCD: CDL-CCD filters block IR, so they will be more suitable for use on cameras without IR filtration such as total defiltered cameras or CCD cameras ⚠️ |
The filter completely blocks the emission lines of artificial light sources such as street lamps (eg sodium and mercury vapor) as well as air glow. All “important” emission lines as well as the spectral range of the night-adapted eye are exceeded. The additional IR blocking layer allows the use of DSLRs and webcams without an integrated IR block filter.
