M83 (Feb2020)
M83 is a barred-spiral galaxy in the direction of Hydra, 15 million light years away and about 55,000 light years across. It is a starburst galaxy and unusually, six supernovae have been observed in it in the last 100 years.
It was one of the first deep sky images I attempted almost 10 years ago. Although it was a reasonable effort, recently I felt it worthwhile to have another go since I've learned so much about the equipment and image processing over that time. Here is the result from data collected on the 21st February.
Takahashi TOA-130/EM 200 Temma 2 mount/SBIG 11000M camera, Astrodon filters; f=1500mm for f11.2, LRGB = 310min, fov ~ 1x0.7deg.
I'm very pleased with the result.
