Veil Nebula, about 4 hours
In summer 2015 I acquiered some 4 hours of light with the then unmodified Canon 1100D and the Canon EF 200mm f2.8L II USM. I gave it another try to see how processing the old raw material turns out, deploying my star handling program. I think the result shows improvement.
