Description

This is image is processed from a Telescope Live dataset acquired from Feb 15, 2023 through Feb 18, 2023.  The telescope is a Planewave CDK 24 with a new QHYCCD QHY600M Full Frame CMOS monochrome camera.

I would hope that Telescope Live will add some NB frames to this dataset in the future, it would be interesting to see if they reveal anything new in M104's structure.  This image is from an LRGB dataset, processed in PixInsight.  The Lum image was processed separately and integrated into the final image as a combination mask and L image for the LRGB channel combination process.

The more I use Russ Croman's tool suite (BXT, SXT, NXT) the more impressed I am.  Color Correction was implemented through the SPCC process.

Roughly the work flow was WPCC (w/1x drizzle), DBE, SPCC, BXT, SXT, (STF, then Color Sat for the RGB Stars).  For the Starless/Galaxy: STF, Russ Croman's color corrected HDRMT script, CRVS, ColorMask+CRV, NXT, DarkStructureEnhance script, Lum channel combination (detailed earlier), the Stars and Starless combination through PixelMath.

My  primary (final) image is a cropped version of the original M104 image to zoom in/enhance the M104 Galaxy.  I have also included the uncropped version for anyone intersted in the full field image captured by the CDK24 telescope.

Please enjoy!!!

From Wikipedia:The Sombrero Galaxy (also known as Messier Object 104M104 or NGC 4594) is a peculiar galaxy of unclear classification in the constellation borders of Virgo and Corvus, being about 9.55 megaparsecs (31.1 million light-years) from the Milky Way galaxy. It is a member of the Virgo II Groups, a series of galaxies and galaxy clusters strung out from the southern edge of the Virgo Supercluster. It has a diameter of approximately 15 kiloparsecs (49,000 light-years), three-tenths the size of the Milky Way.It has a bright nucleus, an unusually large central bulge, and a prominent dust lane in its outer disk, which is viewed almost edge-on. The dark dust lane and the bulge give it the appearance of a sombrero hat (thus the name). Astronomers initially thought the halo was small and light, indicative of a spiral galaxy; but the Spitzer Space Telescope found that the dust ring was larger and more massive than previously thought, indicative of a giant elliptical galaxy.The galaxy has an apparent magnitude of +8.0, making it easily visible with amateur telescopes, and is considered by some authors to be the galaxy with the highest absolute magnitude within a radius of 10 megaparsecs of the Milky Way. Its large bulge, central supermassive black hole, and dust lane all attract the attention of professional astronomers.
