Whirlpool Galaxy

The Whirlpool Galaxy, also known as Messier 51a (M51a) or NGC 5194, is an interacting grand-design spiral galaxy located in the constellation Canes Venatici. It was the first galaxy to be classified as a spiral galaxy. The Whirlpool Galaxy lies 7.22 megaparsecs (23.5 million light-years) away from us and has a diameter of 23.58 kiloparsecs (76,900 light-years). Its companion, NGC 5195, is easily observed by amateur astronomers, and both galaxies can be seen with binoculars.

M101 Pinwheel galaxy

The Pinwheel Galaxy, also known as M101, is a stunning spiral galaxy located in the constellation Ursa Major, about 21 million light-years from Earth. With a large, nearly face-on orientation, it displays beautiful, well-defined spiral arms filled with bright blue star clusters and reddish regions of active star formation. M101 is known for its striking symmetrical structure and massive size, spanning about 170,000 light-years across, making it almost twice the diameter of our Milky Way.

My first attempt to capture this galaxy was 8 years ago. This time I am equipped with a new camera and significantly improved processing skills:

M63 Sunflower galaxy

Messier 63 is a stunning spiral galaxy located about 37 million light-years away from Earth in the constellation Canes Venatici. The galaxy gets its name from the striking pattern of dust and gas that resembles the petals of a sunflower surrounding its bright yellow core.

The Sunflower Galaxy was first discovered by the French astronomer Pierre Méchain in 1779 and later added to the Messier catalog by Charles Messier in 1781. With an apparent magnitude of 8.6, it is easily visible with a small telescope or binoculars.

Spring is a great time to observe galaxies like Messier 63 because, during this season, the Earth is oriented in such a way that we are looking out towards the outer regions of our Milky Way galaxy. This means that the sky is darker and clearer, providing ideal conditions for observing distant galaxies.

NGC 6744 Galaxy

NGC 6744 is a galaxy in the constellation Pavo. The galaxy has beautiful spiral arms, which attracted my attention and I spent 4 hours collecting the light coming from this 28 million light-years distant deep space object.

M83 Southern Pinwheel Galaxy

Messier 83, sometimes called Southern Pinwheel Galaxy is one of the most difficult deep space objects in the whole of Messier’s catalog. It is located between the constellations Hydra and Centaurus. This galaxy has a very low southern declination (close to the horizon) and this makes it difficult to photograph in Central Europe. I tried a few years ago in La Palma, but my attempt was ruined by clouds and bad weather in general. This time I was better prepared: traveled south and hired a telescope with a much longer focal length. However, after the acquisition in the post-processing stage, I noticed that the final image is not that sharp and it was not really publishable. I was quite disappointed and put the picture in the archive. Recently I came back to this image because a new tool for sharpening was released – BlurXTerminator. I must say, this plugin for Pixinsight makes magical things. It reduces the stars and simultaneously makes the non-stellar object significantly sharper. I managed to turn an unfocused picture into this:

NGC 5128 Centaurus A Galaxy

NGC 5128 Centaurus A is a galaxy, which can be found in cancellation, you can guess which one, Centarus. This galaxy is not visible from Europe or from the northern hemisphere. If anyone wants to observe or photograph it, he has to go south. And this is precisely what I did. I went to Namibia, specifically to an Astrofarm Kiripotib. I went there with a plan and this Galaxy was my first and primary target. As for most galaxies, one needs a long focal length. Therefore, I rented a telescope there. Specifically, it was Meade 10″. I brought my own focal reducer TS 0.67 and attached my old ASI071. I made in a total of 133 pictures, each 3 minutes long, and stacked them together. This means nearly 7 hours of exposure time. The dust cloud blocking the light from the galaxy really popped out with the little help of deconvolution.

M99 Galaxy

This beautiful spiral galaxy is listed under number 99 in Messier’s catalog. It can be visually located during the spring months in the southwest corner of the constellation Coma Berenices. The galaxy has several spiral arms, which are the product of the interaction with another galaxy. This interaction also induced very high angular velocity, which is the highest in Messier’s catalog. Specifically, the outer parts move with a velocity of 1200 km/s with respect to the center of the galaxy.

I dedicated two nights to this galaxy. The telescope was collecting two whole nights the light traveling 45 million light-years. In total, the picture is a stack of 130 single shots, each 3 minutes long.

NGC 253 Sculptor Galaxy

Every time when I chase the darkness in southern lands, I try to capture some deep space objects in the southern hemisphere, which are not visible from Central Europe. One of these objects is the Sculptor Galaxy, which can be found, surprisingly, in the constellation Sculptor (south from Aquarius). Here are some features: it is approximately 11 million light-years away from us, it has roughly 90 000 light-years in diameter (similar to Milky Way) and it is characteristic by the intense star formation. This galaxy is sometimes called Silver Coin or Silver Dollar Galaxy, but I pushed the colors into the yellow spectra, therefore it looks like a gold coin.

M101 Pinwheel Galaxy

Messier 101 is a beautiful spiral galaxy, which can be located in the constellation Ursa Major. If I look back to my older picture, I must admit, it is worth spending a long time and dedicating some capture time for the hydrogen alpha channel.

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.

M87 Virgo A Galaxy

I came back from La Palma, disappointed by the weather. Surprisingly, back home was nice Moonless weather, so I took my telescope out and captured Messier 87, which is bright and super massive galaxy in constellation Virgo. It’s one of the largest elliptical galaxy in observable universe and makes the central sport in galactic cluster in Virgo. This galaxy contains a lot of globular clusters, approximately 12000. In comparison our Milky Way contains only 200.

I am really happy that I captured this galaxy this year, because quite recently was the first photo of a super massive black hole in M87 was captured. I think everybody got across the orange picture, which was an effort of many scientists.

M83 Southern Pinwheel Galaxy

Messier 83 is a spiral galaxy located in constellation Hydra. It is one of the brightest and closest (15 million light-years) galaxies observable from Earth. On the other hand there are much brighter and closer galaxies, for example Andromeda is only 2.5 million light-years away and M33 Triangulum Galaxy is roughly 3 million light-years away.

Due to the fact that the M83 has very low southern declination (rises not far from horizon), thus it is very difficult to capture from light polluted Central Europe, I decided to take a trip to south. Specifically to La Palma (Canary Islands) and tried to photograph it from there. I had only one clear night out of ten, but together with M68 was this galaxy my primary target and I somehow managed. My plan was to capture more deep space objects, but the weather didn’t allow me.

M61 Galaxy

Spring offers the best conditions for photographing/observing of the galaxies. This is caused by the fact that the constellations Virgo, Leo and Coma Berenices are visible and there are galaxies anywhere you look. This year, I already captured M58 M88 M89 M90 M91 Galaxies, but there are still some galaxies missing, in order to finish Messier catalogue. One of them was M61 (upper left corner). This spiral galaxy is located in constellation Virgo, it has about the same size as our home galaxy Milky Way and it is approximately 52 light-year away from Earth.

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.

M74 Phantom Galaxy

Messier 74, sometimes called Phantom Galaxy, is a galaxy located in the constellation Pisces. This galaxy has two prominent spiral arms and it is a typical example of a spiral galaxy. The distance of 35 million light-years from Earth has been estimated, therefore what we are looking at here is a 35 million year old picture.

The photo was taken in Schwarzwald under decent dark skies and it’s an integration of 45 photos, each 3 minutes exposure, i.e. more than 2 hours of exposure time in total.

NGC6946 Fireworks Galaxy, NGC6939 Ghost Bush Cluster

NGC 6946, sometimes called Fireworks Galaxy, is a beautiful spiral galaxy located between constellations Cepheus and Cygnus. It is approximately 22.5 million light-years away from Earth and it’s a part of Virgo Supercluster of galaxies. The name didn’t get from the shape, but due to frequent explosions of supernovae.

Next to the galaxy is located NGC6939 Ghost Bush Cluster, which is a part of our own Galaxy, therefore the distance from earth is “only” 4000 light-years.

The picture is the last one from the day. I slewed to target, switched on auto guiding and went to sleep. Therefore the picture is an integration of 73 photos, each 5 minutes long, i.e. 6 hours of total time. This is probably the picture with the longest integration time from Milos.

M33 Triangulum galaxy

This is third galaxy captured on Milos. First I was not able to resist and captured Andromeda, second one was Barnard’s galaxy and third one is this one M33 galaxy in constellation Triangulum or simply Triangulum galaxy. Andromeda galaxy (biggest), Milky Way (second biggest) and Triangulum (third biggest) form local group of galaxies. M33 has diameter approximately 60 thousand light-year, which makes it half size of the Milky Way and the light from there has been traveling roughly 3 million years.

NGC6822 Barnard’s Galaxy

NGC6822 is a galaxy located in the constellation Sagittarius and it is 1.6 million light-years from Earth. This galaxy belongs to a local group of galaxies with Andromeda, Triangulum Galaxy, and Milky Way. This galaxy is quite famous because Edwin Hubble discovered several variable stars in this galaxy. These variable stars can be used for the determination of the distance from Earth. Barnard’s Galaxy was the first galaxy to accurately determine distance.

Barnard’s Galaxy is a very dim deep space object; therefore I dedicated quite a long integration time to it (180 minutes) and I chose a long exposure time for each frame (300 seconds). Several nebulae are visible in the picture. These are the red spots located on the left side of the galaxy. Bubble Nebula and Ring Nebula are giant HII regions, where new stars are born.

M31 Andromeda galaxy

After capturing many clusters I wanted to switch to more interesting objects, which would test the quality of the skies on Milos, therefore I slewed my portable newton telescope to probably the most famous galaxy – Andromeda. During the post-processing I was astonished how many details were revealed after such short integration time. I would not be able to capture such picture from home, even if I would use any light pollution filters and much longer integration time.

Brief description of the galaxy: Andromeda is our galactic neighbor and it is approximately 2.5 million light-year from Earth, but it is approaching (110 km/s). There are estimates that our Milky Way and Andromeda will collide, but we still have some time, because it should occur in 4.5 billion years. Andromeda has diameter 220 thousand light-years, which makes it twice bigger than our own galaxy Milky Way. Two clouds surrounding the main galaxy are dwarf galaxies M32 and M110.
