M16 Eagle Nebula

H II nebula

1 Comment

Eagle Nebula is probably the most known deep space object, due to one picture from the Hubble Space Telescope. The pillars of creation were detected, where the new stars are born. I already captured this nebula by using narrowband filters and a monochrome camera. This time I used a different approach – a one-shot color camera + a new IDAS NB1 Nebula Filter. This filter should completely suppress the light pollution from sodium lamps and partially from LED lamps, passing the most interesting wavelength of H-alpha, OIII, and H-beta. In my opinion, it works well even in my light-polluted home.

Antares Cluster DSO Fuerteventura Globular cluster M4 MaxField coma corrector Messier4 Newton 150/600 Rainbow Astro RST135 Scorpius ZWO ASI071MC Pro

Messier 4 (left side of the picture) is a globular cluster located in the constellation Scorpius, close to the brightest star of this constellation Antares (right side). This cluster is the closest one to the Solar System, due to its “short” distance of 7200 light-years and it contains several tens of thousands of stars. There is another globular cluster on the bottom side of the picture NGC 6144. The star Antares is classified as a red supergiant, with a diameter several times bigger than the Sun, which makes it one of the largest know stars. it is only 550 light-years away, which means M4 and Antares are close only visually, but in reality, there is a very long distance between them.
If any brighter star is photographed by the Newtonian telescope, the diffraction cross appears due to the so-called “spider vanes” holder of the secondary mirror. If the spider vanes are not perpendicular to each other (like in my case), the diffraction pattern makes multiple ugly lines. This means I will have to correct it, as soon as I get back from Fuerteventura.

Canary Islands DSO Emission nebula Fuerteventura HII region Lobster nebula Nebula Newton 150/600 NGC6357 Rainbow Astro RST135 Scorpius TS MaxField coma corrector ZWO ASI071MC Pro

Lobster Nebula is a HII region (giant cloud of excited hydrogen gas) located in the constellation Scorpius. The nebula rises only 8° above the horizon in Central Europe, which means, it is submerged in light pollution caused by nearby towns, villages, or cities. The situation is completely different on the Canary Islands, where the nebula rises 27° above the horizon. Therefore, this nebula was the primary target of my expedition to Fuerteventura. Unfortunately, the weather didn’t cooperate and strong winds caused bad seeing and didn’t allow me to capture more frames. So, next time it will be better.

Messier 24 is a spiral arm of our galaxy located in the constellation Sagittarius. The region is heavily populated by the stars, which makes you think how big our home galaxy Milky Way is.

Dark nebula DSO Fuerteventura IC4604 MaxField coma corrector Nebula Newton 150/600 Ophiuchus Rainbow Astro RST135 Reflection nebula Rho Ophiuchi ZWO ASI071MC Pro

Rho Ophiuchi is a triple star system (on the left side of the picture) in the constellation Ophiuchus. The light from the stars is partially absorbed by the gas, which makes the blue reflection nebula visible. A smaller reflection nebula called IC 4603 is located on the right. The picture shows just a small frame of the significantly bigger nebula, called the Rho Ophiuchi complex, which combines star Antares, globular cluster M4, and many more reflection, emission, and dark nebulae. In order to capture the whole complex, one has to use a significantly shorter focal length, like 130 – 200 mm.

The picture was taken under the dark skies of Fuerteventura and it’s a stack of 73 pictures, 3 minutes each, which makes the total integration time 219 minutes.

Messier 7, sometimes called the Ptolemy Cluster, is an open cluster located in between constellations Sagittarius and Scorpius. The cluster is visually located on the galactic plane of the Milky Way, therefore there are many stars in the background. The cluster is badly visible from Central Europe. Much better opportunities to observe or photograph this cluster have astronomers or astrophotographers in southern countries. My last attempt to capture it in Greece was constantly disturbed by the weather, therefore when I was again in the South, specifically at Fuerteventura, I didn’t hesitate and recapture this beautiful cluster.

Messier 5 is a globular cluster located in the constellation Serpens. I revisited this cluster after four years. Such a spectacular deep space object simply deserves more attention, than I was able to spend four years ago. At that time I used the same telescope but now I have a different coma corrector and camera. Moreover, this time I dedicated significantly longer integration time, specifically I was collecting the photons 2.7 hours, which were traveling to us 24 500 years.

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.

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.

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.

Messier 53 is a globular cluster located in constellation Coma Berenices.

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.

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.

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.
