I decided to spend one more night shoot the Flying Dragon Nebula. Combined now the image contains 3 hours of lights. The result is much better than before, but the nebula is still very very faint… the longer exposure reveals more details in the faint nebula from the great wings of the dragon. Anyway, it would need much more exposure time…
Total 72 lights (25 x session 1, 47 x session 2) x 150s, f/5.6, ISO1600 (total 180min integration time)
