The following is taken from Lumicons website:

For Deep-Sky Photography Only
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.

Recommended Films
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.
Filter Factor
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.


The filter I have for sale is as new, no marks anyplace on the glass or even on the filter ring itself (including the threads).

It comes in the original case and cushioned foam. The case shows some wear from being moved from here to there, but no cracks or chips and seals tightly.

Also included is a 77mm lens hood which has never been used.

Buy a step-up (or step-down ring) and it will fit almost any size lens.

Asking $60 including shipping or a straight trade for a 72mm Kenko
R-64 in like condition.

Clear, dark, steady skies.
