The filter enhances the contrast between all deep-sky objects and the background. \u003cbr\u003e\u003cbr\u003e The CLS-CCD Filter enhances the contrast between astronomical objects and the background. Due to the wider transmission curve compared to UHC filters, a greater amount of light will pass the filter. Stars will be less dimmed. This filter has been optimized to block as much spurious light as possible and simultaneously provide the best performance for useful light. A good filter for DSLR-, CCD- and film b\/w-photography as well as observation of deep-sky-objects with telescopes or photo lenses of all aperture f\/3 and above. \u003cbr\u003e\u003cbr\u003e The filter blocks completely emission lines of artificial light sources like streetlights (e.g. sodium- and mercury-vapor) as well as the airglow. All important emission lines as well as the spectral range of the night-adapted eye are being passed. The supplementary IR-blocking layer allows the use for DSLR- and Webcams without an integrated IR-block filter. \u003cbr\u003e\u003cbr\u003e Other uses for the Astronomik CLS CCD Light Pollution Filter include easier resolution of Double Stars and with the EOS-Clip model, photography with DSLR cameras is feasible even under extreme light-polluting conditions without shifting the white balance. The 1.25-inch and 2-inch socket models can be used for observations from light-polluted areas. If you plan to create color images from emission line data, our CLS-CCD filter is a great choice for the Luminance channel.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: #000000;\"\u003e\u003cstrong\u003eAstronomik CLS CCD Light Pollution Filter - 50mm Round Features:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e92-\u003cspan\u003epercent\u003c\/span\u003e transmission at 486nm (H-beta)\u003c\/li\u003e\n\u003cli\u003e92\u003cspan\u003e-percent\u003c\/span\u003e transmission at 496nm (OIII)\u003c\/li\u003e\n\u003cli\u003e92\u003cspan\u003e-percent\u003c\/span\u003e transmission at 501nm (OIII)\u003c\/li\u003e\n\u003cli\u003e97\u003cspan\u003e-percent\u003c\/span\u003e transmission at 656nm (H-alpha)\u003c\/li\u003e\n\u003cli\u003ePass from 450 to 540nm and from 640 to 690nm\u003c\/li\u003e\n\u003cli\u003eParfocal with other Astronomik filters\u003c\/li\u003e\n\u003cli\u003eGlass thickness: 1mm\u003c\/li\u003e\n\u003cli\u003eCompletely resistant against high humidity, scratches and aging effects\u003c\/li\u003e\n\u003cli\u003eDiffraction limited, the filter will not reduce the optical performance of your telescope!\u003c\/li\u003e\n\u003cli\u003eAstronomik filters are delivered in a high-quality, long lasting, filter box\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eOPT Product Number: \u003cb\u003eAK-CLSCCD-50R\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Astronomik","offers":[{"title":"Default Title","offer_id":45012879933482,"sku":"fss1793373947490","price":125.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0723\/0999\/7610\/files\/astronomik-cls-ccd-light-pollution-filter---50mm-round_1.jpg?v=1793373953","url":"https:\/\/pinehem.shop\/products\/astronomik-cls-ccd-light-pollution-filter-50mm-round","provider":"My Store","version":"1.0","type":"link"}
