Here is my latest attempt at imaging the famous Eagle Nebula (M16) in Serpens Cauda using Hydrogen alpha, Oxygen III and Sulphur II filters. These three images were built from 34 x 20 minutes exposures for H alpha, 27 x 30 minute exposures for OIII, and 26 x 30 minute exposures for SII. The raw data were recorded during a run of clear nights back in July 2016.
Ultra deep mate. Should print that on a large canvas.
