Canon 5Ds and Sigma 20mm f/1.4
Using Affinity Photo, I adjusted the contrast, saturation, colour temperature, clarity, and noise reduction.
Last night we had some delightfully pink auroras. This pink fringe is caused by nitrogen molecules getting excited by charged particles at an altitude of about 100 km. March is statistically one of the best months for auroras, so I am hoping for more shows in the near future.
