Introducing a must-have telescope filter for any astrophotographer that doesnt
happen to live on Mauna Kea. With the Orion SkyGlow Astrophotography Filter you
can take incredible deep-sky images under light-polluted skies with your CCD or
DSLR camera. Thats 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. Youll 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 Orion
SkyGlow Astrophotography Telescope 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 Orion SkyGlow Astrophotography
Filter is remarkable. Just look at the filtered and unfiltered actual image
