Description: An image created from 111 total exposures of durations 5, 10, 20, 30 and 60 seconds, on one night, combined with calibration frames (flats, darks, biases) for noise reduction and editing. The image was taken using the ZWO ASI 294MC Pro cooled dedicated astrophotography camera, on a Skywatcher 80ED telescope, on a Skywatcher EQ5 Pro mount, guided using PHD2 and the ZWO ASI 120mm Mini camera. The frames were stacked and edited with SiriL. The galaxy is 31 million light years away and 76,000 light years in diameter. It is interacting with another galaxy, which is the clear smaller circle next to it.
