Hi All,
I did this excercise with two goals:
1) Practice my Post-processing
2) Try to see what can you get from terrible light polluted skies
I live in Buenos Aires, one of the most light-polluted cities in the world, from the middle of the city I took 30 light frames, 15 dark frames with a fixed tripod, Canon 5DII and a 90mm F2.8 lens, ISO3200, 6 second exposures.
I tried to see If I could get the lagoon nebula but it's not visible even with binoculars so I tried to "guess" where it would be.
I processed the stacks with DSS then removed the background and stretched the histogram with IRIS, final touches in Photoshop.
I realize the exposure time was too long as the stars are a little oblong to my taste. Yet there it is! at the bottom of the frame the Lagoon Nebula is visible. M7 rules the frame at the top
. Do you see other interesting objects?
