NGC7023 Iris nebula

Iris nebula, known as NGC 7023, is a reflection/dark nebula located in constellation Cepheus. It’s 1300 light years far from the Solar system and it has 6 light years in diameter. In the middle of the nebula rules so called baby star, which is only few thousand years old. The star was created partially from the gas which is now illuminated.

The picture was taken under dark skies of Greek island Karpathos during my 2019 expedition. Unfortunately, the weather was very bad. There wasn’t a single cloud on the sky, but it was extremely windy, therefore I got only one single steady night and this night I wanted to capture also other deep space objects. Therefore the picture is a stack of only 37 pictures, each 2 minutes long.

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.

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.

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.

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.

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.

NGC 2237 Rosette Nebula

Rosette Nebula is a giant cloud of hydrogen gas. The gas is ionized by the star cluster located in the middle and therefore emits the light. Circular shape and the color correspond to the name – the rose. The cluster in the middle can be observed even by using small telescope, but the nebulosity is very dim, therefore in order to see it, one would need perfectly dark sky and very large telescope with low magnification. It’s definitely easier to photograph the nebulosity. My previous photo was done through the narrow band filters, which suppress the light pollution and increases the contrast of the picture. Now I tried it with normal one shot color camera and I must conclude that it went quite well.
