Here is a quick widefield view of Messier 17 (cataloged as M17 or NGC 6618), also known as the Omega Nebula or Swan Nebula, it is a star-forming region in the Milky Way galaxy. It's located in the constellation Sagittarius, about 5,500 light-years from Earth. M17 is a vast cloud of dust and gas that's roughly 15 light-years in diameter and has a mass of around 800 solar masses. It's part of a larger cloud that's about 40 light-years in diameter and has a mass of 30,000 solar masses.

Some old narrowband data from last year reprocessed.
I felt a little guilty as I let a clear spell of several nights pass by without attempting any imaging, and now it's cloudy again for the foreseeable future. So I had a play with some old images to make up for it all.

This image of our neighboring galaxy Andromeda (M31) was taken at Grand Mesa Observatory on October 2nd 2019. It's a combination of 300 second LRGB and Ha images, with a total integration time of approximately 7.5 hours, the H Alpha which helped bring out the red nebulae in the spiral arms of the galaxy.
Processing was done using Pixinsight and Photoshop, with mentoring from Terry Hancock, director of the Grand Mesa observatory and downunderobservatory.com tutorials.

Markarian's Chain is a stretch of galaxies that forms part of the Virgo Cluster. When viewed from Earth, the galaxies lie along a smoothly curved line. Charles Messier first discovered two of the galaxies, M84 and M86, in 1781. The other galaxies seen in the chain were discovered by William Herschel and are now known primarily by their catalog numbers in John Louis Emil Dreyer's New General Catalog, published in 1888. It was ultimately named after the Armenian astrophysicist, Benjamin Markarian, who discovered their common motion in the early 1960s. Member galaxies include M84 (NGC 4374), M86 (NGC 4406), NGC 4477, NGC 4473, NGC 4461, NGC 4458, NGC 4438 and NGC 4435. (ref: Wikipedia)

This is the open cluster designated NGC 7419 in the constellation Cepheus. This cluster is between 7,500 and 11,000 light years away. Its location is behind some dark nebulae which reddens the color of the stars. The cluster does contain no less than five red supergiant stars - this is one of my favorite open clusters!

I am working on some advanced PixInsight processing techniques - star reduction among them. This technique is often warranted in images, like the original East Veil that I posted yesterday, where stars overwhelm the target. The star reduction technique that I am using required the use of StarNet to produce a copy of the image that does not have stars.
There are noticable artifacts of some of the larger and brighter stars, but that is ok because the larger and brighter stars will remain unchanged when stars are added back to the image. With the stars removed, what I thought to be be fairly clean image actually contains a lot of noise. I can also see gradients that I thought that I had removed.
In addition to using StarNet for star reduction, I can see it as a usefull tool for checking the adequacy gradient and noise reduction.
Among the other advanced PixInsight processing techniques that will add to my workflow are linear and non-linear noise reduction, and linear fit to pre-balance average intensityh the RG&B channel images,
The Trifid Nebula (Messier 20/NGC 6514) is an H II region in the north-west of Sagittarius in a star-forming region in the Milky Way. It was discovered by Charles Messier on June 5, 1764. Its name means 'three-lobe'. The object is an unusual combination of an open cluster of stars, an emission nebula (the relatively dense, reddish-pink portion), a reflection nebula (the mainly NNE blue portion), and a dark nebula (the apparent 'gaps' in the former that cause the trifurcated appearance, also designated Barnard 85). Viewed through a small telescope, the Trifid Nebula is a bright and peculiar object, and is thus a perennial favorite of amateur astronomers.
