Description

m42 close-up and its trapezium cluster(Theta Orionis A ,B, C and D. I was no able to discriminate Theta Orionis E and F) capture in LRGB with different setup to get a compromise of resolution and dynamic range. The lucky imaging settings are as follows:
0.5s x 6250 frames, 2000 frames selected, aligned and stacked with Siril.
