Description

So this was by far the hardest image to edit for me so far! Partly because there was a gradient in the lower part of the image, exactly where the dark nebulosity is in the bottom left corner. Additionally, it was the first image I (at least partly) used Pixinsight on and even though it was quite overwhelming and a lot to learn, the deconvolution alone proved to be a very subtle but insanely effective tool.

The image was taken with fairly short exposures which proved to be difficult in the stacking process due to insanely large amounts of data but on a positive note: no star-trailing! (as I am not yet guiding that was a bit of an issue in the past)

I hope you like the image because I really cannot go on editing it for another week ^^ Feedback is as always very welcome.
