Globular Cluster - NGC 6752
Taken using my Sony A6000 and the 200mm kit lens. Tracked using an AZ-GTI.
Total exposure time is 15mins.
[From Wikipedia]
NGC 6752 (also known as Caldwell 93 and nicknamed the Great Peacock Globular) is a globular cluster in the constellation Pavo. It is the fourth-brightest globular cluster in the sky, after Omega Centauri, 47 Tucanae and Messier 22, respectively. It is best seen from June to October in the Southern Hemisphere
Messier 2 (M2 or NGC 7089) is a globular cluster, approx 55 kly away, in the constellation Aquarius. It is 175 ly in diameter, contains about 150,000 stars, 13 billion years old and one of the largest and oldest globulars in our galaxy.

47 Tuc the other great southern globular cluster.
A great sight in any size scope and visable to the naked eye as a blury star.

12 x 120 second L-R,G,B images bined 1x1 & combined using Sigma-Reject. Taken from Wind Canyon just West of Silver City, NM
Taken at MPAS, Briars Historical Park, 14th of October. Seeing conditions were fairly marginal due to moisture? causing high levels of sky glow. Other than that very steady seeing from the guiding results.

Aside from the SMC and LMC, probably the best galaxy in the southern hemisphere.
L'amas globulaire M3.
Image réalisée en empilant près de 400 clichés réalisés avec une caméra couleur Altaïr GP-Cam sur un télescope Skywatcher 750/200 (télescope Newton de 200 mm de diamètre). Le logiciel Deep Sky Stacker a été utilisé pour empiler les photos et le traitement final a été fait avec GIMP. Le choix discutable d'équilibrage des blancs automatique avec le logiciel de capture Altaïr astro sur un flat réalisé avec un drap et une lampe de poche, et le traitement ultérieur, ont donné une couleur bleue ou rose aux étoiles peu brillantes et une teinte verte aux plus brillantes...
Globular star cluster. It sits 14,800 light years away from us and is over 170 light years wide.
Distance from the Sun to Pluto is 5.5 light-hours by comparison!
Globular cluster in Hercules. 9 min worth of exposure using a Canon 450 D and an Orion 190 MN telescope.
M22, nifty globular cluster in Sagittarius - a big ball of roughly 70,000 stars packed into a ball only 100 light years across.
Edited NOIRLab image of the Small Magellanic Cloud. Color/processing variant.
Original caption: Part of the SMASH dataset showing what is arguably the best wide-angle view of the Small Magellanic Cloud to date. The Large and Small Magellanic Clouds are the largest satellite galaxies of the Milky Way and, unlike the rest of the satellite galaxies, are still actively forming stars — and at a rapid pace.
M13 imaged through my Short Tube 120 as a test image, unguided. The night had gusty winds and poor seeing, so I was limited to 15 & 30 second exposures. Given the conditions, I rather like this image!

"M92 is one of the brightest globular clusters although often overlooked in favour of M13 which also lies in the constellation of Hercules.
The cluster is located about 27,000 light-years from Earth, and is thought to be at least 11 billion years old. It contains roughly 330,000 stars with a tightly packed core and has a diameter of about 109 light-years. It has a relative velocity of -112 km/s."

M30 is a globular cluster in the constellation Capricornus. I don't know what is happening, but I am not managing to reach focus properly. Maybe the telescope is out of collimation.

One of the brightest star clusters in the sky is visible as a cloudy, blurred star in the left hand side of the photo
The globular cluster known as Messier 3 or M3 is one of the most impressive and fascinating objects in the night sky. Located in the constellation of Canes Venatici, M3 was first discovered by Charles Messier in 1764 and has been a favorite among astronomers ever since.
M3 is a densely packed cluster of stars, with over 500,000 stars contained within a radius of just 90 light-years. This cluster is located approximately 33,900 light-years away from Earth and is one of the largest and brightest globular clusters in the northern hemisphere.
One of the most interesting features of M3 is the presence of blue straggler stars, which are clearly shown in the image. These stars are unusual because they appear to be younger than the cluster itself. It’s believed that these stars are formed through interactions between pairs of stars, where one star steals material from its companion, resulting in a rejuvenated star.
M3 has been studied extensively by astronomers using a variety of instruments, including the Hubble Space Telescope. These observations have provided valuable information about the structure and dynamics of the cluster, as well as general insights into the formation and evolution of globular clusters.
The bright star in the lower right hand of the frame is an 8th magnitude double star cataloged as HD 119391.
This is a dramatic improvement over my last image of this object, taken in 2019. New telescope, new mount, new imaging equipment, and a technological leap forward really makes a difference.
Image Info
This is the second imaging run with the RC-12 Astrograph, and is a normal LRGB image. I kept the individual subframe exposures short (120s) to prevent burn-in of the core.
Interestingly enough, this imaging run occurred with an 11-day-old moon in the sky about 45 degrees away from M3. It didn’t seem to affect the background brightness much, and could be entirely processed out. Note to self: you can image globulars and open clusters in LRGB with a largish moon in the sky.
