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.

M40 Double Star

Messier 40 is a double star located in constellation Ursa Major (in the middle of the picture). Charles Messier was searching for the nebula in this part of the sky, which was observed by Johannes Hevelius. He was unable to locate any nebulous object, but he found this double star and catalogued them under the number 40. Double star should be a system of two stars, which are bonded by the gravity, but the latest measurements demonstrated that these two stars are close to each other only visually and they are completely unrelated.

M101 Pinwheel Galaxy

Messier 101 is a beautiful spiral galaxy, which can be located in constellation Ursa Major. If I look back to my older picture, I must smile, how I overdone the saturation and whole post-processing. Such beautiful galaxy deserves to be re-captured and processed again:

M102 Spindle Galaxy

Galactic season continues. After capturing M64 galaxy, I pointed my telescope to another one. Specifically to Messier 102 called Spindle Galaxy, which is a lenticular galaxy in constellation Draco. Afterwards I went to sleep and the telescope was collecting the photons coming from there. The light had to travel very long distance, because this galaxy is approximately 40 million light-years from Earth.

M64 Black Eye Galaxy

Messier 64 is a galaxy, which can be located in constellation Coma Berenices. The name “Black Eye” or sometimes “Evil Eye” got from the central dark cloud, which blocks partially the light coming from there. This galaxy is relatively close to us – only 17 million light-year, which is significantly less compared to visually neighboring galaxies in constellation Virgo.

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.

M76 Little Dumbbell Nebula

Messier 76 is one out of four planetary nebulae in Messier catalogue. It is one of the dimmest objects in this catalogue. The nebula is located in constellation Perseus and it is 2500 light-years away from Earth. M76 was discovered by Pierre Méchain in 1780 and in the same year was catalogued by Charles Messier.

The picture is a stack of 58 pictures, each 180s, which means nearly 3 hours of the integration time. However, the conditions were far from optimal, because the Moon was in first quarter and illuminating the skies.

M37 Open Cluster

Messier 37 is the largest and the brightest open cluster in constellation Auriga. Visually, it has two deep space neighboring open clusters M36 and M38. The cluster was discovered by Giovani Battista Hodierna in 1654 and catalogued by Charles Messier in 1764. The cluster contains a lot of red giant stars and it is approximately 4500 light-year away from Earth.

This is the second deep space object, which I captured in a single night. The clouds rolled in, therefore I was able to capture only 30 pictures, 60 second each.

M36 Open Cluster

Messier 36 is an open cluster located in constellation Auriga, not far from the bright star Capella. The cluster is approximately 4000 light-years from Earth and it has diameter 14 light-years. There are another two open clusters in the vicinity. Specifically it is M38 (north-west) and M37 (south-east).

The picture is a stack of 50 images, each has 60 s exposure time, which means less than hour of the integration time. Another Messier object was captures. I hope, I will finish the whole Messier catalogue this year.

M78 Nebula


Messier 78 is a reflection nebula located in constellation Orion, visually not far from stars Alnitak Alnilam and Mintaka, which form the Orion’s belt. This nebula is one of the brightest reflection nebulas on the sky, due to reflection of the light coming from two bright stars called HD38563A and HD38563B.

My previous attempt to capture this nebula during my expedition to Schwarzwald was not that successful, due to the due problems, therefore I dedicated nearly 3 hours to this DSO. However, it looks like the picture would need longer integration time.

M77 Galaxy


Messier 77 is a spiral galaxy located in constellation Cetus and it is approximately 47 million light-year away from Earth. Due to its diameter 170 light-year, this galaxy is one of the biggest objects of Messier Catalogue.

The galaxy in the bottom right corner is called NGC 1055, which together with M77 creates binary system.

The picture is a stack of 20 pictures, each 3 minutes long, i.e. only one hour of integration time. This is obviously not enough for such deep space object, but I wanted to capture another DSO this night. Moreover, I was not able to wait till 1 o’clock, when the street lamps are switched off, because at this time, this galaxy was nearly reaching the horizon.

Now it’s time to slew to M78 Nebula.

M103 Open Cluster


Messier 103 is an open cluster located in constellation Cassiopeia. With its distance 8500 light-year from Earth, this cluster is one of the most distant clusters from Messier’s catalogue.

The picture is a stack of 56 pictures, each 2 minutes long, i.e. nearly two hours of integration time. December is a month, which is rich with deep space objects, but it’s also rich with clouds. In whole December I got only single opportunity to take my telescope outside, therefore this is not the only deep space object, which I captured this night.

M35 Shoe-Buckle Cluster

Messier 35 an open cluster located in constellation Gemini. The cluster is approximately 2800 light-year far from Earth and it contains roughly 200 stars.

Second open cluster NGC 2158 is located in the background (upper right part of the picture). I didn’t know that there is another cluster in field of view. If I would know it, I would change the composition of the picture.

This cluster was the last one out of four captured during single night. In the early morning I slewed to M35 and went to sleep. The camera captured 56 exposures, 3 minutes each, before the dawn arrived. This means nearly 3 hours of total exposure time.

M38 Open Cluster

Messier 38 is an open cluster located in constellation Auriga. It has diameter 25 light-years and it’s approximately 3500 light-year away from Earth.

I managed to capture two open clusters this night already (M39 and M34) and there is still one to go (M35). Therefore I didn’t dedicate a lot of time on M38 – this means that the picture is an integration of one hour of exposure time.

M34 Open Cluster

After capturing M39 I slewed the telescope to another deep space object. Specifically to an open cluster Messier 39. This cluster is located in constellation Perseus and it is approximately 1400 light-years away from Earth and it has diameter roughly 24 light-years.

The picture is a stack of 72 two minute subframes, which means 144 minutes of total integration time.

M39 Open cluster

Messier 39 is an open cluster located in constellation Cygnus and it’s only 825 light-year away from Eartch. The cluster is visually located on the galactic plane of the Milky Way, therefore there are so many stars in the background.

I already captured M39 two years ago, but with different camera and different coma corrector. This time I used slightly bigger sensor and brand new corrector TS MaxField. This corrector should reduce the focal length by 5% and also due to the larger sensor I got bigger field of view compared to my previous picture. However, the corrector is not capable of eliminate the coma fully and in the corners are the stars elongated. I spent some time by adjusting the tilt, but this obviously didn’t solve the problem. This means that the only corrector which is capable of eliminating the comatic aberration fully is Explore Scientific HR CC.

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.
