Eagle Nebula - M16 SHO - 20Jul-14Aug2020
 
© Mariusz Goralski


My latest image of the Eagle nebula (M16/NGC6611) in the constellation Serpens, this time imaged through narrowband filters using my 8" Celectron SCT, at F10 - 2032mm focal length, with my astromodded and active peltier cooled Canon 40D DSLR.

The color channels are SII, HAlpha and OIII as RGB, and color balanced to remove the heavy green color cast created by the strong Hydrogen Alpha signal.

The total exposure time spent on this image was 20 hours and 57 minutes consisting of the following subs exposures:

RGB: 13x15s, 19x30s, 17x60s, 12x90s, 17x120s, 15x180s

HII: 2x600s, 9x900s, 4x1200s

OIII: 1x600s, 8x900s, 1x1200s, 11x1500s

SII: 2x500s, 14x1800s

All at ISO1600.
