The Thousand Rubies Galaxy  (千のルビー銀河) Messier 83

I photograph this galaxy every year, and I learned that it has the name ``A Thousand Ruby'', so this time I took a picture of it with that image in mind.
Neither Signal nor Edit specifically boosted Ha, but there are certainly a lot of rubies.
It was a galaxy with a relatively pale blue color.
