Another re-image of an old friend will the new ASI 6200 camera.
I cropped the original to a convenient 9400x6200 then 940x620 and resample.
I used a new workflow:
The L is HDR composite of 15s, 30s and 45s from combination of all RGB 45s images.
Both L & RGB StarXterminated and then NoiseXterminated. Level 3&4 HDRM applied to L.
RGB stars from StarXterminator added back in in PS using Linear Dodge.
From Wikipedia:
Messier 58 (also known as
M58 and
NGC 4579) is an
intermediate barred spiral galaxy with a weak inner ring structure located within the
constellationVirgo, approximately 68 million
light-years away from
Earth. It was discovered by
Charles Messier on
April 15, 1779 and is one of four barred spiral galaxies that appear in Messier's catalogue. M58 is one of the brightest galaxies in the
Virgo Cluster. From 1779 it was arguably (though unknown at that time) the farthest known astronomical object until the release of the
New General Catalogue in the 1880s and even more so the publishing of
redshift values in the 1920s.
