M72 is a collection of stars, formally known as a globular cluster, located in the constellation Aquarius roughly 50,000 light-years from Earth. The intense gravitational attraction between the closely packed stars gives globular clusters their regular, spherical shape. There are roughly 150 known globular clusters associated with the Milky Way galaxy.

*Omega Centauri - NGC 5139, or Caldwell 80* This is a globular cluster in the constellation of Centaurus that was first identified as a non-stellar object by Edmond Halley in 1677. Located at a distance of 17,090 light-years (5,240 pc), it is the largest known globular cluster in the Milky Way at a diameter of roughly 150 light-years. It is estimated to contain approximately 10 million stars, and a total mass equivalent to 4 million solar masses, making it the most massive known globular cluster in the Milky Way. Omega Centauri is very different from most other galactic globular clusters to the extent that it is thought to have an origin as the core remnant of a disrupted dwarf galaxy. *Observation data* Class: VIII Constellation: Centaurus Right ascension: 13h 26m 47.28s Declination: −47° 28′ 46.1″ Distance: 15.8 ± 1.1 kly (4.84 ± 0.34 kpc) Apparent magnitude (V): 3.9 Apparent dimensions (V): 36′.3 *Physical Characteristics* Mass: (4.05±0.1)×106 M☉ Radius: 86 ± 6 ly Estimated age: 11.52 Gyr Other designations: NGC 5139, GCl 24, ω Centauri, Caldwell 80, Mel 118 *Captured on*: __Feb. 14, 2021... *Equipment*: __TSOptics Photon 12" F4 Advanced Newtonian... __TSOptics 0.95 reducer and coma corrector... __SoftwareBisque Paramount MX Mount... __Nikon D750 DSLR Camera .... *Processing Details*: __47 x 30 sec. each frame (23 min. 30 sec. data) __17 dark frames __ISO-1270 __Stacked in DSS __Processed in PixInsight __Enhanced in LightRoom & Snapseed *Location:* __Chiguru Farm, Bilikal Forest, Karnataka *Sky Conditions* __Bortle Scale 3.8 __Clear Sky __Few surrounding villages lights interference #OmegaCentauri #globularcluster #nightsky #astronomy #softwarebisque #astrophotography #starrynight #cosmos #AstroPhotographyIndia #nikon #Travel #karnataka #india © Vijay Kapoor Follow My Instagram for More pics: http://Instagram.com/lunar_mountains_climber https://www.instagram.com/p/CLhAZjRpH0U/?igshid=11im8w3zhn5bp

M13 - Great Globular Cluster - Hercules Constellation This is the final process of the image I posted a week and a half ago. Normally, I wouldn't post a reprocess so fast, but with the major differences in the core and color, I wanted to make sure I got this out before moving on to other targets. Globular clusters are really neat targets but with my current focal lengths, there is not a lot of practical ones for me for me go after. Getting images of these targets is different then how I normally inage: no reducer, no filter, etc. Processing is also a different animal. Overall, really happy with how this ended up . 90x60s 20 darks, 50 flats, dark flats and biases 400 ISO - Bortle 8 .

M13 “The Great Globular Cluster in Hercules” - A globular cluster is a spherical collection of stars, gravitationaly bound to each other, that orbit the core of a galaxy. This particular cluster is is approximately 145 lightyears in diameter. M13 contains several hundred thousand stars. It can be visible to the naked eye (depending on viewing conditions) but individual stars can’t be made out without the help of a telescope. It’s also worth noting that these stars are extremely old. Thought to be 12-13 billion years in age, they are almost as old as the universe itself! I don’t remember how much data was accumulated to create this image as it was shot in early summer 2020.

M5

Esta época es buena para los cúmulos globulares. M5, en la constelación de Serpens, está situado a casi 25000 AL de casa. Un placer observarlo.

Meet Omega Centauri - one of the largest globular clusters in the Local Group residing in our very own Milky Way. Containing over 10 million stars ✨ , some of which can be as close as tenth of a light year, Omega Centauri may have been a dwarf galaxy that was swallowed whole by the Milky Way. While most of the stars are gravitationally bound by its central black hole, some such as the nearby Kapteyn’s Star ⭐️ do escape. .
