M72 Globular Cluster in Aquarius

Messier 72 is a globular cluster, which can be located in constellation Aquarius. The cluster is approximately 55 light-years from us, which makes it one of the distant objects from Messier catalogue. M72 is very special deep space object for me, because it’s the last object of Messier catalogue captured by me. Now I am thinking, shall I continue and try to capture NGC catalogue? Or shall I move to southern hemisphere? I am definitely sure that some of the Messier’s objects need to be recaptured.

M13 Great Globular Cluster in Hercules

In my opinion, Messier 13 is the most beautiful globular cluster in our galaxy. Last time when I photographed this cluster, I used focal reducer (don’t ask me why), therefore I decided to recapture it with focal length 1060 mm. Small galaxy in upper right corner is called NGC 6209.

M10 Globular Cluster

Messier 10 is a globular cluster located in constellation Ophiuchus. This cluster belongs to one of the closest to the Earth – the distance is “only” 14 300 light-years. It has visually many globular neighbors: M12 northwest, M14 east and M107 southwest.

M12 Globular Cluster

Messier 12 is a globular cluster located in constellation Ophiuchus. The cluster is 15,700 light-years away from Earth and contains approximately 200,000 stars. There are another two globular clusters in the vicinity: M10 south-east and M14 east.

M53 Globular Cluster

Messier 53 is a globular cluster located in constellation Coma Berenices. This cluster is quite far from galactic center of the Milky Way (60 000 light-year), which makes it to be located on the outer edge of our galaxy. However, it heading towards the center with speed approximately 63 km/s. The cluster contains 500 000 stars, but this cannot be verified by the photo I took, because it is 58 000 light-year from Earth and my telescope has very small aperture to resolve this kind of details.

M68 Globular Cluster

Messier 68 is a globular cluster located in constellation Hydra. The cluster contains more than 100,000 stars and it is approximately 33,000 light-years away from Earth. The best time for observation is between March and July. Observers from Central Europe have disadvantage, because M68 doesn’t raise much above the horizon. Therefore this cluster was one of my primary targets on La Palma, where M68 is much better visible. However, the weather was bad and I only got 40 minutes between the clouds.

M79 Globular cluster

Messier 79 is a globular cluster located in constellation Lepus. This cluster is particularly interesting, because it can be observed/photographed only in winter and there is no other globular cluster in that part of the sky. Most of the globular clusters are visible in summer, when the galactic center is shows its beauty. This means that most of the globular clusters are close to the galactic center, but M79 is actually at the edge of our galaxy. Diameter of our own Milky Way galaxy is approximately 100,000 light-years. M79 is roughly 60,000 light-years far from galactic center and 42,100 light years away from earth. The study conducted in 2003 revealed the concentration of the stars in constellation Canis Major, which is neighboring constellation to Lepus and it was assumed that there is a dwarf galaxy there. Latest studies disproved this theory and the star concentration is assumed to be caused just by the spiral arm of the Milky Way.

This deep space object is extremely difficult to capture due to its very low declination if observed from Central Europe. Moreover, also the optics was not cooperating this night. I must admit it’s the worst picture of a globular cluster I have ever made. But if I want to complete Messier catalogue this year, I have to publish it as it is. I hope I will get an opportunity to recapture M79 next year.

M2 Globular Cluster

Messier 2 is a globular cluster located in constellation Aquarius and it’s approximately 37’000 light-year away from Earth. It’s one of the biggest known globular cluster, because it contains approximately 150 000 stars and it has 175 light-years in diameter. After Crab Nebula M1, this cluster is the second object of Messier’s catalogue of deep space objects.

This picture was the second captured object (after M71) during one night and it’s an integration of 3 hours of exposure.

M71 Globular cluster

Messier 71 is a globular cluster located in constellation Sagitta. The cluster is located approximately 12 – 13 thousand light-years from earth. The classification of M71 as a globular cluster was questionable for a long time, because it lacks central star concentration and therefore it was considered as an open cluster. The diameter of this cluster is only 27 light-years, which is very low value for globular cluster.

Well I am back in light pollute sub-urban area. I can use bigger and heavier telescope, but I am missing dark skies of Milos. The picture is an integration of 38 pictures, with exposure time 3 minutes. Total exposure time was approximately 2 hours.

I managed to test new TS-Optics 2″ 3-element MaxField Newtonian Coma Corrector, which should be 2” version of Wynne corrector. It should have significant advantage compared all 2” coma correctors on the market: it reduces focal length by 5%, should correct full frame CCD (we will see about that) and it should have very low vignetting. I will have to extend my World Wide Coma Correction exercise.

M70 Globular cluster

Messier70 is a globular cluster located in constellation Sagittarius. The cluster is at a distance approximately 29’300 light-years from the Solar System. Neighbor cluster M69 was captured during the same night.

M70 is the 15th globular cluster captured by me on Milos Island – mission accomplished.

M69 Globular Cluster

Messier69 is a globular cluster located in constellation Sagittarius. It is approximately 29’700 light-years away from Earth. Together with Messier70 are close to galactic center of Milky Way (distance between them is 1’800 light-years) and there were two last deep space objects captured on Milos Island. These two were the last missing Messier objects, which I wanted to capture and I was very happy that I managed.

M19 Globular Cluster

Messier 19 is a globular cluster located in constellation Ophiuchus and it is approximately 29000 light-years far from Earth. This cluster is particularly interesting by its oval shape and most probably it’s the most oval globular cluster in our galaxy. The cluster, just like M9, is quite close to the galactic center.

The picture, like many others, was taken on island Milos, under dark Greek skies and it’s an integration of 58 minutes of the exposure.

Messier 56 is a globular cluster located in constellation Lyra. M56 is one of less bright globular cluster, because its distance from Earth is 30’700 light-years.

This is the third (M54 and M55) globular cluster captured in single night and the picture is an integration of 63 frames, each 3 minutes long, i.e. 189 minutes total exposure time.

M54 Globular Cluster

Messier 54 is a globular cluster located in constellation Sagittarius. It has been assumed that the cluster’s distance is 50’000 light-years. Recently (1994) it was discovered that this cluster doesn’t belong to Milky Way galaxy, but it’s a part of Dwarf elliptic galaxy in Sagittarius and it is approximately 86’400 light-year from Earth. This means M54 is first discovered globular cluster outside of our galaxy.

Messier M4 is a globular cluster located in constellation Scorpius. It has approximately 100 000 stars and it’s roughly 7200 light-years away from us, which makes it one of the closest globular clusters to the Solar system. Hubble Space Telescope discovered many white dwarf stars, which are the oldest known stars in our galaxy, having an age of 13 billion years.

The picture was taken during my travels to Greek island Milos and it’s only integration of 24 of two minutes exposures. This means only 48 minutes in total.
