Processing Experiment on M16 from a One Shot Color Camera
(Note: This image was an experiment in processing. It was taken with my 80mm refractor. I plan on replacing it soon with a much larger number of frames from my larger Ritchey-Chretien 152mm telescope. That will give me more data and resolution.)
Messier 16 The Eagle Nebula with One Shot Color Camera. The Eagle Nebula is rich in colors, but while narrowband filters will keep the colors separate, it's difficult to have the proper color separations when using a one shot color (OSC) camera. This image was made with 25 exposures at 300 seconds each on a ZWO ASI294MC Pro one-shot color camera cooled to -5C and with the Gain set to 120. The key to showing multiple colors in the nebula was adjusting colors through the use of range masks for successive areas surrounding the core in Pixinsight software. Final touchup was in Adobe Photoshop Creative Cloud software. Acquisition of the exposures was with Astrophotography Tool software, and guiding was through an Orion 50mm 242 FL guide scope using a ZWO ASI183MC camera connected to PHD2 auto-guiding software. The mount was a Skywatcher EQ6-R Pro. The target was very low on the horizon, but the use of an STC Astro Duo Narrowband filter helped clean things up a bit.
