This target is best suited for longer focal lengths but at least with a larger FOV I was able to include a distant galaxy arm or IFN into the frame.
An inverted image seems to show a connection between the arc and the the galaxy.
From
Hubble site:
"Located in the constellation Hydra, this colorful, swirling spiral galaxy is known as M83. A "starburst" galaxy, M83 is considerably smaller than our own galaxy but is producing stars at a much faster rate. The pink clouds of hydrogen gas that dot the galaxy's spiral arms are the nurseries where new stars are being born. The blue, grainy clumps mixed in with these star-forming regions are clusters of hot, young stars that have blown away the surrounding gas with their fierce ultraviolet radiation. Some of these young stars are only about a million years old. The yellow glow closer to the center of the galaxy comes from more mature stars that have lived for 100 million years or more. "
The total exposure time is more than 70hrs including14hrs Oiii that didn't add any useful details to the image.
L : 24.8 hrs
G : 8.9 hrs
R : 8.2 hrs
B : 8.7 hrs
Oiii: 14.0 hrs
Ha : 9.3 hrs
Three little galaxies were left out of the field cropping the image; from top to bottom: PGC718484, PGC47964 and PGC47968.
In the outer region of M83 a spiral galaxy and a barred galaxy with a ring: PGC724525 (top), PGC48132 (bottom)
