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 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.
