Here is Omega Centauri taken with the Telescope Live CHI-1 telescope and using 11x R, 11x B, 10x G, and 10x L, all 300 seconds each. This gives a total of 3 hours and 30 minutes of exposure. I processed it in APP, PI, and Photoshop. If you zoom in on the full size image you can see nice separation on the stars, whether in the core or the edges. I think this is the best globular cluster I have processed out so far.
I have a subdued one that has more color in the core, and a brighter one. I will let you decide which you like better.

Solar Active Region 3053
Photographed on July 8, 2022
I had clear skies, and great seeing which allowed me to photograph this spectacular active region on the sun. I feel like the coming years are going to produce some amazing solar activity as we inch closer to solar maximum.

Cygnus Cloud over the Observatory's Dome of Kattameia (Halpha-RGB )
Date : 1st July 2022
This photo covers the area from North America and Pelican Nebulae to Sadr region nebulae (IC 1318 / gamma Cyg nebula , NGC 6914 , IC 1311 , NGC 6888 / Crescent nebula )
Kottamia Observatory is the largest telescope in the Middle East and North Africa. The telescope, which is located 80 km from the center of old Cairo, has a main mirror diameter of about 1.88 meters (74 inches) and weighs about 2 tons, The diameter of the dome is about 19 meters, and weighs more than 100 tons.
The Observatory was established in 1964 and it is located in the perfect place far from light pollution. But nowadays there is a new extension of Cairo called the New Governmental Capital located about 13 km form the observatory, so the north- western horizon of the observatory is fully light polluted and the north-Eastern to south- eastern horizon is at Bortle scale 3.
Multiple shockwaves colliding have shaped the surrounding dust into the beautiful, intricate detail of the Crescent Nebula seen in Cygnus. Also included in this image is The Soap Bubble Nebula. This extremely faint nebula is a fairly recent discovery around 2007-2008 and designated PN G75.5+1.7. The brightest star in the image is 34 P Cyg. It was first thought to be a nova but is now designated as a Hypergiant Luminous Blue Variable. It is one of the most luminous stars in our galaxy.

M14 Globular Cluster or Stars. KG Observatory, Julian, CA.
My goal here was to go deep or go home. (-:
Over several days I collected many 60s subs, but only kept the 429 best between 1.4" and 2".
24 5 minute RGB subs (2 hours per color) were then collected between 1.8" and 2.6".
With this bright object and the number of subs, noise reduction is minimal to help preserve the faintest stars and several tiny galaxies.
"M14 (NGC 6402) is a globular cluster of stars in the constellation Ophiuchus. It was discovered by Charles Messier in 1764.
At a distance of about 30,000 light-years, M14 contains several hundred thousand stars. At an apparent magnitude of +7.6 it can be easily observed with binoculars.
The total luminosity of M14 is in the order of 400,000 times that of the Sun corresponding to an absolute magnitude of -9.12. The shape of the cluster is decidedly elongated. M14 is about 100 light-years across.
A total of 70 variable stars are known in M14, many of the W Virginis variety common in globular clusters. In 1938, a nova appeared, although this was not discovered until photographic plates from that time were studied in 1964. It is estimated that the nova reached a maximum brightness of magnitude +9.2, over five times brighter than the brightest 'normal' star in the cluster."
After my LRGB version, Here is a new version of the seahorse nebula (Barnard 150) with the integration of Ha layer.
A more colorful version.
I hop you'll like it !

STORY:
In this image taken on the road that leads to the El Tatio Geysers, in the Atacama Desert in Chile, we can see part of the southern arm of the Milky Way, where we can more easily find the Running Chicken, Eta Carinae and Gum nebulae. Just below, we can also see the Large Magellanic Cloud, our neighbor galaxy, and two of the brightest stars that can be seen in the night sky, Canopus and Avior.
It is worth noting that at the time of this capture the moon was still in the sky, reducing the visibility of these elements a little.
This is the Atacama sky, one of the best in the world for astrophotography.
