Night Nineteen - Back to the Sombrero Galaxy

Image
I returned to the Sombrero Galaxy to see if there had been any improvement of skills since it was last visited. this galaxy has a prominent dust lane in its outer disk, which from Earth is viewed almost edge-on. The dark dust lane and the bulge give it the appearance of a sombrero hat (thus the name). Here is the image from last night 4/25/25: Enlarged version:

Night Eighteen - Markarian's Chain

Image
This is a string of galaxies in the constellation Virgo. M84, M86, and M87 are the largest galaxies of the group, cataloged by Charles Messier. The galaxies may appear small, but each of them contains more than 400 billion stars or more. Messier was a comet hunter who lived in the 1700's. If you are the first to discover a new comet, you get to name it. Messier would name the latest comet after the King's newest girlfriend and would then in exchange recieve a nice gold token from the King. Today we look at those fuzzy objects that Messier discovered and realize that they are a mix of nebulae and galaxies that we can resolve with our more powerful modern telescopes.

Night seventeen - Sombrero Galaxy M 104

Image
Went back to the Sombrero Galaxy last night and did a 3 hour image with a shutter speed of 60 seconds. Disappointed with the drifting creating a slight oval to star shape even though the calibration of the EQ Mode had been excellent. Should have stayed at a 30 second exposure. Longer exposure doesn't equal more information collected. Did some post processing with the JPEG image as fits and png both seemed beyong my basic skills at this time a good project to return to once skill set is upgraded.
