Re: [APML] H-alpha solar photography nightmare

["Bert Katzung" <katzung1@attbi.com>]

Hi "Vega" (are you also Emmanuele?):
So you have the setup that Steve Barnes mentioned --- very different from
the ordinary H-alpha filter that most of the rest of us are familiar with! I
guess I do remember seeing some images of solar prominences in the old
Lumicon ads. Are there any instructions with the setup that you are working
with? I wonder how many of these things are out there? I don't think I've
ever seen one on Astromart. Let us know if you get it worked out.
