| Barnard 33 Filters
I was wondering if anyone is able to tell the if the hydrogen-beta filter is required for photography of barnard 33, or if its for visual observing? I know its supposedly "necissary" for visual observing (which suprises me as it has such a bright magnitude rating), but do I have to have it to photograph it?
Barnard 33 being the horsehead nebula.
Clear Skies,
