IDAS H-alpha enhanced UV/IR Blocking Filter for Canon APS-C frame camera [HU-HEUIBII-EOS]

HU-HEUIBII-EOS
$199.00 USD
1 in stock IN STOCK, usually ships within 48h or less directly from our Canadian warehouse
Astro Hutech: The IDAS HEUIB-II (H-alpha Enhanced UV IR Blocking) filter is designed for enhanced spectrum DSLR's and one-shot color CCD astronomical cameras.
Besides removing the IR and UV ends of the spectrum which are often out of focus in refractive optics, it isolates the common H-alpha line relative to the surrounding extreme red end of the spectrum, making it easy to bring out the faint H-alpha emission nebulosity of astronomical photos, yet retain the background color balance of broadband photos.
Available in 52mm and 48mm sizes mounted in standard camera filter rings, 37mm size mounted for the Canon MFA, and unmounted in 36mm and 49mm sizes. The filter is also available as a Nikon front filter.
Some comparison shots taken with the enhanced Canon 6DH (standard Canon UV/IR blocking filter vs. HEUIB-II filter) show a clear difference both in background sky color balance and contrast of H-alpha nebulosity in the extremely faint object IC1396. Note the good background color balance as shown in the histograms of the individual color channels of the HEUIB-II filtered image.
The HEUIB-II filter also returns normal daylight color balance to spectrum-enhanced cameras as can be seen in this photo at right taken with normal DSLR auto-white-balance (AWB) enabled.
