M78 Nebula

The M78 Nebula, also known as Messier 78, is a bright reflection nebula located in the constellation Orion, about 1,350 light-years from Earth. Known for its striking blue color, M78 is illuminated by the light of young, hot stars embedded within it. The nebula’s dust particles reflect this starlight, creating a luminous glow that highlights its wispy clouds and dark lanes of dust. M78 is one of the brightest reflection nebulae in the sky and is a fascinating region of active star formation, where new stars continue to emerge within dense pockets of gas and dust.

IC 4304 Rho Ophiuchi Nebula

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.

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.

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.

IC59 IC63 Gama Cassiopeia nebula

Is a reflection nebula located in constellation Cassiopeia, approximately 600 light years from Solar System. This nebula is very dim, therefore I used narrow band filters Ha, OIII and SII and composed two pictures. One is composed in real colors, second in fake (Hubble) color palette.


NGC7023 Iris nebula

Iris nebula is one of the most difficult deep space object to capture. Not the nebula itself, but the dark clouds around it. In order to capture these clouds you have to be under very good skies – with minimal light pollution. The reason is simple – the clouds are dark, but the background as well, therefore if you want to visualize the contrast between something which is dark and something which is even darker, good skies are essential. Since I live in sub-urban area, I had to wait till 1 o’clock at night. At this time nearly all street lamps are switched off and the light pollution drops to acceptable level.

Anyway back to the nebula – it’s reflective nebula (similar to Pleiades) located in constellation Cepheus. It’s 1300 light years far from the Solar system and it has 6 light years in diameter.
