This is a collaboration between Thomas Engl and myself.
We collected the data for this project in 2015 and 2016.
I also made some RGB pictures, but was not able to "fill" the deep luminance with it while keeping a natural touch to the picture.
Now, a few years and projects later, I gave it another try.
L: 219*300 sec
RGB: 6*1200 sec and 21*300 sec each
Total exposure time: 46,5 h
Skywatcher Esprit 100
TS triplet apo 102 mm f/7 with 0,79 Photoline reducer
6" f/3 Boren Simon
