Home Filters Astro Imaging Filters Altair Astro Premium CLS-CCD UV/IR Filter 1.25 Inch
The Altair Astro Premium 1.25" CLS-CCD Filter is designed for imaging applications with DSLR, CCD or CMOS cameras as a solution to controlling unwanted wavelenghts of light from artifical sources. Although primarily designed for astrophotography this filter can be used for visual observation with larger telescopes giving similar results to ultra high contrast filters.
The Altair Astro CLS-CCD Filter Drastically reduces the effects of light pollution and natural moon or skyglow, permitting long exposure imaging, even in urban conditions. Aside from the high qualty Schott German glass and top quality coatings, these filters have some additional enhancements which make them ideal for your astro imaging application. Advanced UV/IR blocking give small star sizes even with refractor optics, and AR (Anti Reflection) coatings reduce halo effects and internal reflections for more pleasing star images. Enhances nebulae with peak transmission in Hß 486.1nm; OIII 495.9nm; OIII 500.7nm; Ha 656.3nm wavelengths. Artificial Light Pollution wavelengths are very effectively blocked, the primary ones being: Hg 435.8 Hg 546.1nm Hg 577.0nm Hg 578.1nmNa 589.0 Na 589.6nm Na 615.4nm Na 616.1nm Can be used visually on larger aperture telescopes for very high contrast. (Do not use for Sun!). Premium filter features:• Batch-tested for consistency.• High quality dichroic/dielectric coatings. • Anti-Reflection coating to reduce star-halos - stackable.• UV/IR block for imaging - star bloat reduction with refractors.• Ultra-flat glass by Schott Germany. • Precision CNC machined filter cell for strain-free mounting and freedom from tilt.
