Altair Astro Premium 2" CLS-CCD filter with UV/IR block and AR coating
The Altair Astro Premium 2" CLS-CCD Filter is designed for imaging with DSLR, CCD or CMOS cameras however it can be used for visual observation from 10" aperture (do not use for solar observation!).
The filter drastically reduces the effects of light pollution and natural moon or skyglow, permitting long exposure imaging, even in urban conditions.
Enhances the contrast background-nebula with peak transmission of 95% in Hβ 486.1nm; OIII 495.9nm; OIII 500.7nm and Hα 656.3nm.
Artificial Light Pollution wavelengths are very effectively blocked, the primary ones being:
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 gives small star sizes even with refractor optics, and AR (anti-reflection) coatings reduce halo effects and internal reflections for more pleasing star images.

Premium filter features
Multi-layer anti-reflection coating to reduce star-halos and reflections from camera optical window.
Batch-tested for consistency.
Ultra-flat glass by Schott Germany. 2.0mm Glass 30sec parallel, optical polish to MIL Spec. MIL-O-13830.
High quality dichroic/dielectric coatings. Electron-beam gun evaporation with ion-assisted deposition coating technology for durability and resistance to scratching, as well as stability on CWL (central wavelength). No deviation affected by temperature change.
UV/IR block for imaging - star bloat reduction with refractors.- 45mm clear aperture to minimise vignetting
Precision CNC machined filter cell for strain-free mounting and freedom from tilt.
