Description

I had that  RGB stack of short exposures 20x30 sec. each filter for a while now and didn´t really know what to do with it.
The fwhm on the combinded image is 0.75" so it was a real magic night.
I croped the field and rotated it by 45 degrees to have the hydrogen bar horizontal.
still not sure if I have done the raw data justice, but even the small field has a dreadful dynamic range and was quite difficult to process.
