Orion 2" SkyGlow Astrophotography Imaging Filter
Ways to Save
Introducing a must-have filter for any astrophotographer that doesn't happen to live on Mauna Kea. With the SkyGlow Imaging filter you can take incredible deep-sky images under light-polluted skies with your CCD or DSLR camera.
That's because Orion custom designed the filter to selectively block the specific wavelengths of light associated with urban sky glow, letting the light emitted from deep-sky objects shine through. You'll see a marked increase in image contrast for all types of deep sky objects, even faint galaxies, which typically are suppressed through visual light pollution filters.
By blocking up to 99% transmission of the offending wavelengths, the SkyGlow Imaging filter enables longer exposure times without background saturation. Because the white light spectrum remains largely intact, the color balance of the image is not affected, eliminating the need for corrective processing later.
The improvement in contrast achieved with the SkyGlow Imaging filter is remarkable. Just look at the adjacent filtered and unfiltered actual image examples. With this filter you can take long-exposure photographs faint galaxies, nebulas, and star clustersfrom a light-polluted city, or from a suburban back yard brightened by a nearby street lamp. Your images will turn out better than you ever thought possible.
The SkyGlow Imaging filter has a threaded aluminum cell and is available in 1.25" and 2" sizes. The 1.25" filter threads into the nosepiece of our StarShoot CCD and similar cameras. The 2" filter fits Orion 2" accessories, including the 2" Zero-Profile camera Adapter that couples a DSLR camera body with T-ring to a 2" focuser.
