The StarGuy UHC, Ultra High Contrast, filter, is designed to give you the best
visual emission nebula views through all telescopes. Manufactured with high quality glass this
filter will bring you amazing views of all emission nebulae. With ultra high light transmission, stars
appear sharp and clear. The UHC Filter
blocks most wavelengths of light pollution and is able to bring the nebular
details--especially in dark skies, but also in moderately light-polluted ones.
Passes the Hydrogen-beta and Oxygen-III lines in the
spectrum so the nebulae are not dimmed, but the background sky's brightness is
reduced over 90%, yielding incredible contrast and making the nebulae appear to
"pop" out of the background sky.
Especially recommended when one purchases a Nebula filter
for general use. If you get just one
filter, this one is it! .
