This was taken during a local star party under central Austin skies. I set up the equipment to step through my narrowband filters so the public could see the change between the filters. It gave a nice talking point to cover the physics of star formation. I binned the exposures so I could get a reasonable signal quickly. It was only displaying on a small laptop screen so resolution wasn't of key importance.
