A first experiment with a Hydrogen-Alpha filter in a DSLR. Noticable loss of resolution with the bayer matrix reducing linear resolution by a factor of 2. See also colour (red) version.

A test of gear, as I intended to image this from darker skies the following night. At 60 seconds in home skies, there is just not enough light available to bring anything apart from Gum 1 (Seagulls head) into this image. See 10/1/2013 instead.
