Orion SkyGlow Imaging 2" Filter - 05561

SKU: ORI-05561

2in. Orion SkyGlow Astrophotography Filter

Introducing a must-have filter for any astrophotographer that doesn't happen to live on Mauna Kea. With the 2" Orion SkyGlow Astrophotography Filter you can take incredible deep-sky images under light-polluted skies with your Charge Coupled Device (CCD) or Digital Single Lens Reflex (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 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 Astrophotography Filter enables longer exposure times without background saturation. Because the white light spectrum remains largely intact, the color balance of the astrophoto is not affected, eliminating the need for corrective processing later. The improvement in contrast achieved with the Orion SkyGlow Astrophotography Filter is remarkable. With this telescope filter you can take long-exposure photographs of faint galaxies, nebulas, and star clusters from a light-polluted city, or from a suburban backyard brightened by a nearby street lamp. Your images will turn out better than you ever thought possible.

The SkyGlow Astrophotography Filter has a threaded aluminum cell and is available in 1.25" and 2" sizes. This 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. The 1.25" filter threads into the nosepiece of our StarShoot CCD and similar cameras. Don't let light pollution spoil your deep-sky images! Get a 2" Orion SkyGlow Astrophotography Filter today and enjoy vivid, high-contrast shots from anywhere!
