Southern Pinwheel Galaxy
My second LRGB image and this is the Southern Pinwheel Galaxy. It was very low over the horizon on Boxing Day at about 2:30am, so it’s really noisy. Looking forward to better results as the season moves on.
This is 10x60s each for RGB and 16
Minutes of luminance. Stacked and processed in PixInsight.
Celestron EdgeHD and Hyperstar. ZWO 1600mm cooled to -15 degrees. Taken from my backyard in noise polluted Melbourne. #southernPinwheelGalaxy #astrophotography
