Description

Checking my hard distks, I have found this 2017 image that was not processed. This image is a wide field area nearby Sirio. It was taken on the 5th of January 2017 from my home terrace. It's the sum of 29 120 secs subs taken with a modded 600d, a Tamron 28-75 at 28 FL f.2.8.

Image has been cropped in order to get rid of huge city sky gradients.

There are a lot of dark structures that I don't know if they are real or just artifacts.

Stacking with DSS, processing (mostly DBE) with Pixinsight.

Thanks for looking
