After ten years of attempting to photograph this magnificent deep space object, I couldn't hold on any longer and had to share what I've done so far.
This is my first image in a year and my first attempt at narrowband processing.
NGC 6188 mapped to the Hubble palette of sulphur II for red, hydrogen alpha for green and oxygen III for blue.
I still need to blend in the LRGB stars to get rid of the purple stars and replace them with natural colours.
This is 24 hours of data, 8 hours in each channel of hydrogen alpha, sulphur II and oxygen III, captured over 18 nights in June, July and August.
I hope you like what I've done thus far.
