this is a shot from summer 07 at my old residence in north liberty indiana. its a prime focus shot from my canon rebel xt 350d through a orion 80mm refractor on a skyview pro mount it was roughly polar aligned and unguided 22second shot! just trying my new camea, wish I would have exposed a longer shot but not a bad shot of M22.
here is a screen shot of the camera info.

Photo taken by Andy Beaton with a new astronomy thingamabobby. Globular cluster M3 in Canes Venatici. See this Blathering for details.
Globular Cluster in Hercules (M92)
A composite of 41 fifteen second exposures thru my Meade LX200 telescope using my Meade DSI imager. The individual captures were calibrated using dark frames in Meade's Envisage software and then stacked and processed using Stark Labs' nebulosity software and Adobe Photoshop CS4. This was imaged on September 2, 2008 between 10:09 PM and ? near Ellenville, NY.
Camera: Nikon D50
Exposure: 12m 50s ISO 200 RGB
Focus Method: Prime focus
Telescope Aperature/Focal Length: 203×812mm
Mount: LXD75
Telescope: Meade 8" Schmidt-Newtonian
Stacked: DeepSkyStacker

This is the globular cluster in Saggita - taken with my 8-inch Meade SCT in my back yard in Portland.
Stacked from the 29 best images out of 70 using Deep Sky Stacker software
Messier 22 Globular Cluster just above the teapot lid of sagittarius. About 10,000 light years away. Bright star at bottom right is 24 sagittarii.
204 x 0.9 second exposures.
Camera was a 1004x-JG modified video camera on a fixed tripod and ball head. 135mm F2.8 M42 screw thread lens stopped to F4. No filters. Camera in gamma mode 1 (highest internal DSP gamma stretching) and gain 75%.
Stacked and gamma stretched in Registax 5, high pass masking in Photoshop Elements.
Distance: 16,700 Light Years; Diameter: 120 Light Years.
Second brightest globular cluster (hence the over-exposure), containing an estimated one million stars.
Globular Cluster in Pegasus (M15)
A composite of 40 thirty second exposures thru my Meade LX200 telescope using my Meade DSI imager. The individual captures were calibrated using dark frames in Meade's Envisage software and then stacked and processed using Stark Labs' nebulosity software and Adobe Photoshop CS4. This was imaged on September 3, 2008 between 12:43 AM and ? near Ellenville, NY.
Edited Hubble Space Telescope image of the Omega Centauri globular cluster. Color/processing variant.
Original caption: An international team of astronomers has used more than 500 images from the NASA/ESA Hubble Space Telescope spanning two decades to detect seven fast-moving stars in the innermost region of Omega Centauri, the largest and brightest globular cluster in the sky. These stars provide compelling new evidence for the presence of an intermediate-mass black hole. Omega Centauri is visible from Earth with the naked eye and is one of the favourite celestial objects for stargazers in the southern hemisphere. Although the cluster is 17 700 light-years away, lying just above the plane of the Milky Way, it appears almost as large as the full Moon when seen from a dark rural area. The exact classification of Omega Centauri has evolved through time, as our ability to study it has improved. It was first listed in Ptolemy's catalogue nearly two thousand years ago as a single star. Edmond Halley reported it as a nebula in 1677, and in the 1830s the English astronomer John Herschel was the first to recognise it as a globular cluster. Omega Centauri consists of roughly 10 million stars that are gravitationally bound. [Image Description: A globular cluster, appearing as a highly dense and numerous collection of shining stars. Some appear a bit larger and brighter than others, with the majority of stars appearing blue and orange. They are scattered mostly uniformly, but in the centre they crowd together more and more densely, and merge into a stronger glow at the cluster’s core.]

Enfin, presque. Finalement, en étant assez rigoureux dans le traitement, on peut s'en sortir, éliminer une bonne part de la pollution lumineuse et garder des détails. Certes les couleurs sont artificielles, mais finalement c'est joli !
Revisiting some old data from 2012. This is the globular cluster M22 in Sagittarius. 13 exposures of 45 seconds each, with ISOs ranging from 1600-2500. Taken with a Canon 50D DSLR attached to a Meade 102mm refractor. [M22 revisited v2]
Well its my Birthday (May 13th), so i figured why not take a shot of M13... :D
My EQ2 was on the fritz. very inconsistent drive rate, so i took 30 shots, in hopes at least a few were usable, 2 ended up being bang on, while 4 more had only a ~2 pixel drift. rest were not good, worst had like 7-8 pixel drift :(
I also took some flats on-site, using a halogen lamp that was on a building about 50 meters away. This worked out perfectly. Sigma 150mm has pretty bad vignetting, so I can tell.

M15 Globular Cluster

Image composed of 3 30sec light images and 16 bias images at ISO 800.
Globular Cluster in Pegasus (M15)
A composite of 54 eight second exposures thru my Meade LX200 telescope using my Meade DSI imager. The individual captures were calibrated using dark frames in Meade's Envisage software and then stacked and processed using Stark Labs' nebulosity software and Adobe Photoshop CS4. This was imaged on August 1, 2008 between 3:05 AM and ? near Ellenville, NY.
We captured the M12 globular cluster in Ophiuchus constellation on July 9, 2020. It is known as the Gumball cluster due to its appearance. This cluster is not too far away from another Globular, M10 in the same constellation. Both were discovered by Charles Messier.
This is a rather loosely packed globularcluster that has an unusually low abundance of low mass stars. Astronomers think that the low mass stars were stripped away by the gravitational pull of the Milky way. It lies 15,700 light years away. It contains about 200,000 stars across a region of space which is 75 light years in diameter.
We captured this image using our Stellarvue Access 80mm refractor and a Nikon D5300 camera. We used the newly ourchased IDAS D1 clip-in LP filter which seems to have worked well. Capture details : ISO 400, f7, and 130 minutes (65x2min) of exposure. Hope you like it!
