(Not
for solar or visual work)
WARNING:
DO NOT LOOK AT THE SUN THROUGH THE LUMICON
Night-Sky H-ALPHA FILTER. Eye Damage could
result from solar heat transmitted through this
filter.
Transmission
for this sharp-cut-off deep-sky photography
filter is zero below 630nm, 90%
at Hydrogen-Alpha 657nm, and
90-98% from 657nm to the near infrared.
Both filter surfaces have high-efficiency anti-reflection
coatings for maximum performance.
The
Lumicon Night-Sky H-Alpha Filter is a powerful
aid in overcoming light pollution, and will help
you achieve strikingly improved results in
telephoto lens B&W astrophotography. It is
ideally matched to hypersensitized 2415 film,
and will reduce light pollution 10-fold, making
it ideal for photography of faint emission
nebulae.To obtain highest relative film speeds,
we recommend using any of the Lumicon HYPER-KITS
to hypersensitize 2415 or other film.
Hypersensitized
Kodak Technical Pan 2415 is the only recommended
film for use with the Night-Sky H-Alpha Filter;
do not use Tri-X or any other B&W film.
Exposures
may be increased 2-10 times with the Night-Sky
H-Alpha Filter, depending on the faintness of
the nebula.
The
Night-Sky H-Alpha Filter is not suitable
for visual use.
