Re: [APML] Hydogen Alpha Deep Sky Filter Source

["John Boudreau" <jeboud@attbi.com>]

Hi Bill,

I'm not familiar with an H-a filter from Lumicon. Are you referring to a
H-beta filter for visual use or an H-alpha for imaging?

Thousand Oaks is a good source for H-beta visual filters. Both Custom
Scientific and Schuler make good H-alpha imaging filters. And Adirondack
Video Astronomy now carries the Astronomik series of filters from Germany
that are worth looking in to.
