Description

It's a dirty galaxy out there but someone has to image it.

It's funny...growing up our parent said, "clean up that dust!" Yet, when the Milky Way does it, we all say, "Ooh! Look at that dust!" It doesn't seem fair.

Anyway, this was my first attempt at something that is primarily a dark nebula. Processing was pretty straightforward:

I used the relatively new NormalizeScaleGradient script for this and it definitely made a small but noticeable improvement.

Dynamic Crop
Deconvolution
ABE
TGV Denoise
Histogram Transformation
