RGB image of Messier 8 - The Lagoon Nebula. Here are the details:

L - 12 x 20 minute subs (no binning, -20c)
R - 9 x 20 minute subs (no binning, -20c)
G - 9 x 20 minute subs (no binning, -20c)
B - 9 x 20 minute subs (no binning, -20c)

Total exposure is 780 minutes or 13 hours (4 hours Lum, 3 hours each for RGB channels). The data was captured with an Astro Physics 12" Riccardi-Honders f3.8 (1,160mm focal length) telescope on a Paramount ME II mount, SBIG STXL16200 CCD camera with Astrodon LRGB Gen II filters located in rural NSW, Australia. The system yields 1.07 arcseconds per pixel resolution and a field of view of 88 x 66 arcminutes.

This is just a quick process after image calibration (Lights, Bias, Darks and Flats) and processing was done in PixInsight. I literally spent 10 minutes after calibration and creating the masters. LRGB only, colour calibration, background neutralization/equalization and two stretches (Histogram and HDR). That is it. No noise reduction, color saturation, nothing.
I also have great Ha and SII masters to work into this image and do a proper job of processing.
