Widefield view of the constellation Scutum, portraying several dark nebula, open cluster M11 and a huge number of background stars that fill the frame with an orange-golden glow.

This dataset had a lot of problems. The green flats were not calibrating well and the dense starfield made it very hard to sample the background. Additionally, this was captured in a white zone, so the my end result has some visible color gradients.
