Stretched using Siril 1.2.0's generalized hyperbolic transformation (independent color channels) in 4 small increments. Specific sets of value, in sequence:

sp 0.00003 (from background selection)
lsi 10.000
sf 2.000
hp 0.50000

sp 0.00060 (from same background selection)
lsi 4.000
sf 2.000
hp 0.50000

sp 0.00624 (from same background selection)
lsi -0.300
sf 1.800
hp 0.50000

sp 0.04000 (increased slightly from same background selection)
lsi -0.300
sf 1.500
hp 0.50000
