NGC 6559 Nebula

If we look in the middle of the night during the summer months (on the northern hemisphere) into the Milky Way’s core, we can find many prominent deep space objects, like Lagoon, Omega, Eagle, or Trifid nebulae. However, there are also not so well known, but also very beautiful, objects. For instance emission nebula NGC 6559, which can be located in constellation Sagittarius. The star-forming region is surrounded by the dark nebula B 91 in the shape of a heart. At the bottom left corner, a part of the Lagoon Nebula is visible.

IC 1318 Sadr Region

Sadr Region, sometimes called The Gamma Cygni Nebula is a giant cloud of ionized hydrogen, located in the constellation Cygnus (Swan). The picture shows only a part of the whole complex. In order to capture the whole nebula, I would need a telescope with a much shorter focal length of the much bigger sensor of the camera. This is actually my second attempt. The first one from Milos Island was quite nice, but this time I dedicated a significantly longer time for this deep space object. Specifically, the picture is an integration of 405 minutes, which means nearly 7 hours in total.

NGC6888 Crescent Nebula

Another cloudless night and I decided to test the IDAS NB1 filter again This time on Crescent Nebula, located in constellation Cygnus. The nebulosity was captured well and it’s comparable to the narrow band image I captured a long time ago. However, the bright stars are surrounded by ugly reflections. I am not sure it’s due to the MaxField coma corrector or the filter. Next time I will try with ExploreScientific coma corrector and we will see.

NGC7000 North America Nebula

After capturing the Eagle Nebula, I was searching for another nebula to test the new IDAS NB1 filter and I picked NGC7000 North America Nebula, switched on autoguiding, and went to sleep. The next morning I processed 138 pictures, each 3 minutes long. Well, I must say that this filter is a very good option for astrophotography in light-polluted locations.

M16 Eagle Nebula

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 – one-shot color camera + 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.

NGC6357 Lobster Nebula

Lobster Nebula is a HII region (giant cloud of excited hydrogen gas) located in 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 Canary Islands, where the nebula rises 27° above the horizon. Therefore, this nebula was my primary target of my expedition to Fuerteventura. Unfortunately, the weather didn’t cooperated and strong winds caused bad seeing and didn’t allow me to capture more frames. So, next time it will be better.

IC 4304 Rho Ophiuchi Nebula

Rho Ophiuchi is a triple star system (on the left side of the picture) in constellation Ophiuchus. The light from the stars is partially absorbed by the gas, which makes the blue reflection nebula visible. Smaller reflection nebula called IC 4603 is located on the right. The picture shows just small frame of significantly bigger nebula, called 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 significantly shorter focal length, like 130 – 200 mm.

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

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.

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.

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.

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.

IC5146 Cocoon Nebula

IC5146, sometimes called Cocoon Nebula, is an emissive nebula located in constellation Cygnus. Central star in the nebula is responsible for the excitation of the surrounding hydrogen gas. On the picture is also captured dark nebula Barnard 168, which creates the strip and it looks like the Cocoon Nebula has a tail.

NGC7293 Helix Nebula

NGC 7293, sometimes called Helix Nebula, is the closest planetary nebula (only 700 light-years away), which can be located in constellation Aquarius. Last year I captured this nebula on Gavdos. This year on Milos I was equipped by different telescope and different camera, so I gave it a try again.

IC1396 Elephant’s Trunk nebula

IC 1396 is a mixture of ionized interstellar gas and dust cloud located in the constellation Cepheus, approximately 2’400 light-years from earth. Due to relative proximity of the nebula, it didn’t fit into the field of view of my telescope/camera. My previous picture, which I captured by the same telescope, was created by using focal reducer and therefore nearly fit into the field of view of even smaller CCD chip. However, under dark skies of Milos, there is no need to use narrow band filters and very nice dark nebulae are nicely visible.

NGC 6888 Crescent Nebula

Crescent Nebula, also known as NGC 6888, is a HII region, hot ionized hydrogen gas cloud. The nebula got the shape by high speed stellar wind of Wolf-Rayet star, which is colliding with slow moving mass, ejected by this star during transformation into a red giant. The nebula is approximately 5000 light-years away from us and it can be located in constellation Cygnus.

The picture is the last one from 6.9.2018. In the evening I captured Omega nebula, M80. As a last deep space object I pointed on Crescent Nebula, started auto guiding and went to sleep. Therefore the picture is a stack of 64 pictures; each has 3 minutes of exposure time, thus total integration time 192 minutes.

IC 1318 Butterfly Nebula, Barnard 347

IC 1318 is an emission nebula, sometimes called Sadr region, located in constellation Cygnus, surrounding bright star Sadr. The star Sadr didn’t fit into the field view of my telescope/camera, but left the trace in form of diffraction spike at the top of the picture. The nebula contains many dark nebulae and the biggest in the middle of the picture is called Barnard 347.

The picture is another demonstration of dark skies of Milos and it is an integration of 77 pictures, each 3 minutes exposure, which means nearly 4 hours of integration time.

M8 Lagoon Nebula

Lagoon nebula (sometimes called Messier 8) is a giant intergalactic cloud of ionized Hydrogen. The nebula is located in constellation Sagittarius and it’s 4100 light-years away from Solar System. It belongs to one of the brightest nebulas visible from northern hemisphere.

I have to admit, this nebula was the main reason and target of the trip to Milos and it was the first deep space object captured there. When I processed the picture I was so happy that the nebulosity is so clearly visible without any narrow band filters. Well, mission accomplished.

NGC281 Pacman nebula

NGC281 is a HII region, which reminds a head of the main character in very popular game from nineties. It is located in constellation Cassiopeia and it 9500 light-year far from us. This nebula was discovered long time ago by Edward Emerson Barnard and it is possible to observe this nebula by reasonable sized telescope under dark skies. Well, I wouldn’t see probably anything, because I live in light polluted area, therefore I had to use narrow band filters, which block the light pollution.

The picture is composed out of 66 narrow band exposures, which means slightly more than one hour per channel. First one is bi-color composition of hydrogen and oxygen, the others are in Hubble palette (hydrogen in green, oxygen in blue and sulfur in red).

IC1848 Soul nebula

Soul nebula is a beautiful HII region, where new stars are being born. It’s located in constellation Cassiopeia and it’s 7500 light-years from Earth. The nebula has neighbor Heart Nebula (IC1805). One can say that in this constellation the heart and soul are close to each other.

As usual, I used narrow band filters to capture this spectacular nebula. It didn’t fit into ma field of view; this means I would need shorter focal length.
