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.

M77 Galaxy


Messier 77 is a spiral galaxy located in constellation Cetus and it is approximately 47 million light-year away from Earth. Due to its diameter 170 light-year, this galaxy is one of the biggest objects of Messier Catalogue.

The galaxy in the bottom right corner is called NGC 1055, which together with M77 creates binary system.

The picture is a stack of 20 pictures, each 3 minutes long, i.e. only one hour of integration time. This is obviously not enough for such deep space object, but I wanted to capture another DSO this night. Moreover, I was not able to wait till 1 o’clock, when the street lamps are switched off, because at this time, this galaxy was nearly reaching the horizon.

Now it’s time to slew to M78 Nebula.

M103 Open Cluster


Messier 103 is an open cluster located in constellation Cassiopeia. With its distance 8500 light-year from Earth, this cluster is one of the most distant clusters from Messier’s catalogue.

The picture is a stack of 56 pictures, each 2 minutes long, i.e. nearly two hours of integration time. December is a month, which is rich with deep space objects, but it’s also rich with clouds. In whole December I got only single opportunity to take my telescope outside, therefore this is not the only deep space object, which I captured this night.
