H-Alpha, O-III, S-II, H-Beta Narrowband Nebular Filter for Astrophotography

Nebula filters let pass certain parts of light where deep-sky objects emit. On the other hand, the unwanted stray light of the cities is suppressed. That allows longer exposure times. You can record fainter objects and gain more information. Nebula filers can be used with DSLR and CCD cameras.

On this page, you can find unmounted filters (31 mm, 36 mm, 50 mm, square ? )

narrowband nebula filters for strong increase in contrast and longer exposure times

filters for specific emission ranges like H-alpha, H-beta, O-II, S-II, for extreme gain in contrast and for false colour images

Baader filter - front side indicator - the black ring always points to the telescope.
