Here's the result from a project cut short by weather...originally I wanted emphasize the HII regions but I wasn't able to gather any amount of NB data. I almost forgot about the data but stacked the <4 hrs and gave it a go today. I was pretty heavy handed in the filter module to push the Ha.
See https://www.astrobin.com/eshu2d/ for details. Since Orion is in prime at the moment I'd like to image something there if weather allows. Maybe I continue next year...

Stefan
