Not as spectacular as M13 a few nights ago, but comes up nicely with Samsung Galaxy S10 and an 8" SCT. Conditions were a bit iffy.

Omega Centauri (NGC 5139) is a globular cluster in the constellation of Centaurus. Located at a distance of 15,800 light-years, it is the largest 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. This photo was imaged using a 8" SCT and a Canon 40D DSLR at 2032mm focal length. The total exposure was 97 minutes, 17x60sec, 12x 150s and 10x300sec subs at ISO800.-

Messier 71 is a globular cluster in the constellation Sagitta. The cluster is at a distance of around 12,000 light years away from Earth and is approximately 27 light years across. This is my first image using an Celestron Off-Axis Guider and it seems to have made a big difference to the overall result. Previously I could not have done 10 minute sub-frames without noticeable distortion of stars. If you want more detail the astrobin link is: http://www.astrobin.com/266668/B -

Messier 56 - A globular cluster in the constellation Lyra. Discovered by Charles Messier on January 19, 1779. It is at a distance of around 32,900 light-years from Earth and measures roughly 84 light-years in diameter, with a combined mass of approximately 230,000 times that of the Sun. The cluster has an estimated age of around 13.70 billion years. It is thought that this cluster may have been acquired during the merger of a dwarf galaxy, of which Omega Centauri forms the surviving nucleus.

While waiting for the Tarantula to get into imaging position to grab some Ha and OIII subs to add to the previous posted image, I decided to do a quick 47Tuc image. Unfortunately when centered, there was no guide star in the OAG at the current setup, and I did not want to alter the position of the OAG since it was still setup from a previous session to continue on NGC2070... so some unguided subs of the glob had to suffice... it's only 15 x 60sec, 15 x 30sec and 15 x 10sec subs in ISO800 at F10 using the modded Canon 40D. Seeing wasn't the best but surprisingly being unguided the stars we© Mariusz Goralski

M3 - Globular Cluster My first attempt at a globular cluster. I had a feeling that this would be a tricky target and I was right. But not bad for a first go. Globular clusters, often referred to as Jewels in the Sky and it's easy to see why. These amazing clusters of stars are orbiting our galaxy and so are actually part of it. This one was discovered in 1764 and is estimated to contain 500,000 stars and around 8 billion years old. It is approximately 33,900 light-years away from Earth.

Apparently this is the largest and brightest globular cluster and yes it is quite impressive. (30 subs 30 sec each ISO 1600 - Image reduced to 50% and cropped to 1080p) -
Hi Guys, I present you the second image taken with my Moravian G4-16000 camera mounted on my modified TeleVue NP101is. Images and technical information below.

After many weeks of telescopes gathering dust I finally managed a long night sketching under the stars. Having only ever sketched open clusters I wanted to attempt a GC. Hercules was well positioned so I chose to draw m92, often overshadowed by the more famous m13. My red torch was a little too bright and there was some intermittent cloud but the sketch comes pretty close to what I saw. All comments / criticisms / comparisons most welcome! Jack p.s. As I was packing up around midnight I saw what I can only assume were parts of a meteorite breaking up in the sky. A long tr

This was taken over 4 nights between the 24th September and 6th October as I have a small windows to view objects in the south due to houses and a great big tree getting in the way. Messier 2, also known as NGC7089 is a globular cluster in the constellation of Aquarius. It is one of the largest know globular clusters and was discovered in 1746 by Giovanni Domenico Maraldi. It lies approximately 55000 ly away and is around 174 ly across.

Hi, Tried to image my favourite globular cluster. Turned out not too bad! Only took umpteen tries to get the colour right, or should I say close. I remember seeing this through my mate's 14 dob at a dark site once, could not stop saying "oh wow", looks so much better than in my 8" LX90. http://www.pbase.com/grahammeyer/image/167207230 Details under image and you can use the size buttons at the bottom also. Thanks for looking.

Omega Centauri (NGC 5139) is a globular cluster in the constellation of Centaurus. This photo was imaged as a side project using my 8SE on the CGEM and the modded Canon 40D at 2032mm focal length. The total exposure was 97 minutes, 17x60sec, 12x150s and 10x300sec subs at ISO800. Clear Skies,

Observation 25-26 July 2017 Date: 25-26th July 2017 @ 19:50 – 2:30AEST Location: Backyard Equipment: 14” Skywatcher GOTO Dobsonian, Televue 31mm Nagler T5 , Televue 17mm Ethos, Televue 11mm Nagler T6, Televue 2X Powermate, Baader Neodymium, Baader Contrast Booster, Astronomik UHC filter. The first thing I noticed from the beginning is that there was more sky glow than I would like, it was quite obvious that the seeing won't be perfect. I keep hunting for maximum magnification and detail on planets so before observation I re-collimated the Dobsonian from scratch. This time I

Hi, I was asked on a Swedish forum to put an "Astronomical Dictionary" on my homepage. I have made a test page in an easy form. Astronomical related words linked to wikipedia. It aims to the beginners in astronomy so it should not be too complicated words. http://astrofriend.eu/astronomy/astronomical-dictionary/astronomical-dictionary.html Let me know if it's useful and and I shall add more words. /Lars

This is a series of 10 minute and 60 second LRGB subs from the Deep Sky West facility in New Mexico. Processing was done mostly in PI, but PS was used for final tweaking. You may need to click the full size image to see the 'propeller'. Luminance: 35x60" bin 1x1 Luminance: 11x600" bin 1x1 Red: 12x60" bin 1x1 Red: 20x600" bin 1x1 Green: 12x60" bin 1x1 Green: 20x600" bin 1x1 Blue: 12x60" bin 1x1 Blue: 20x600" bin 1x1 Which I think makes exactly 13 hours.

We had a moonless, clear night here in Sweden on 2016-05-04. Unlikely as it is, the sky was also very transparent and with unusually good seeing, and with temperatures above zero! I promptly forgot how tired I was after work and set out to observe and image. Started with M5, lying low. Nikon D40X, DSLR with Baader MKIII comma corrector, at the primary focus of a 200 mm f/5 Skywatcher 200 PDS newtonian, mounted on a EQ5 dual axis mount. Light pollution won't allow me to take long exposures that low in the sky (images taken at higher altitude on the same night came out much better), so for start

Here comes another result from the beautiful moonless night we had here in Sweden on 2015-05-04. This time with M13, one amongst the most beautiful objects in the northern sky. This cluster was at a higher altitude than the previously shown image of M5, it is brighter and I also used 18 frames, instead of just 10, so the image is understandably of better quality than that of M5. As you see, the background sky isn't dark. This is because by this time of the year we do not have astronomical darkness anymore at 60N. As before, Nikon D40X DSLR fitted with Baader MKIII coma corrector, at the primar

This is a three hour RGB image taken last week with a straight out of the box skywatcher Pds 8" newtonian and an Atik 314L mono camera and baader filters. I seem to be getting some kind of internal reflection around the mirror clips? any thoughts suggestions welcome Thanks for looking!

The bright, almost fully illuminated moon doesn't interfere as drastically with bright objects like globular clusters as with fainter, less condensed targets. This is an RGB image of M3 - I never bother to make L exposures with globulars these days, the signal is generally strong enough in the colour channels not to need it. Minimal processing - just stretching and a little sharpening in PI. 12" TS/GSO RC at F/8 on a Mesu 200. Atik 383l+, AtikEFW2, ATIK OAG, Lodestar X2, Baader 36mm filters R=G=B = 5 x600s binned 2x2. Click on the image and then select "Full Size" if you wa

M3 From the other night, naff conditions, so I was surprised it came out this way. Very short exposures, but being so bright I could get away with it. Equipment used was a skywatcher MN190, an Atik 314L plus mono. Plenty of exposures though at 40 x 10 seconds.

I am a newbie and would appreciate some advice on viewing globular clusters. . I view from Wisconsin, USA which is at 43 degrees latitude. I am using an Orion 6in f/5 (FC750) Newtonian reflector telescope mounted on a SkyWatcher AZ4 mount. I have upgraded the 25mm and 10mm Plossl eyepieces that came with the telescope with TeleVue 18.2 Delite and TeleVue Nagler 5 eyepieces. I have had good views this summer of Jupiter, Saturn, Mars and the Moon and now want to move on to globular clusters Since I currently have a good view of Scorpius, I have been trying to visualize globular cluster

One of the largest and brightest globular clusters, M3 is about 33,900 light-years away from Earth and contains around 500,000 stars. 26 x 30 second exposures at 6400 ISO plus 10 dark frames and eight flat frames. Processed in Deep Sky Stacker and Photoshop CS6.

A quick sketch from the 1st September (sorry - date is wrong on the image). M15 was still fairly low in the east but the central condensation of stars really stood out, even in a 5.5inch scope. The bright field star intruding on the edge of the image was distracting. If I had a tracking mount I'd have banished it permanently! A lot of the extended GC was on the threshold of vision and the resolved stars faded in and out. M15 will always have a special place for me as it was the first GC i ever saw Thanks for looking. Jack
