Thanks. These are 6 shots. 5x15min + 1x5min, stacked in StarStax. The picture was kind of experiment but I like the result

Amazing! A great shot you'd almost don't think is possible.
It would be interesting to know more of the technique behind it.

I just read your comment, so I will give some info about the picture.
First you need a good tripod and you have to fix your camera toward the pole. The pole is the center of the circles. It is different for the northern and the southern hemispheres. Also you can use a compass or/and take a test picture.

In my case these were 5 pictures, 15 minutes each plus one 5 minutes which gave final exposure of 80 minutes.
The other camera settings were ISO 1250 and f4.0.
Process as you wish in your favorite RAW converter, you can make it lighter or sharper or apply other corrections.
The final step is to stack the pictures in one final picture. There are different software capable of doing this. I liked the result from StarStax.

Just to mention that it's better not to wait much between exposures because waiting results in gaps in the arcs (the arc is the path of a star). If you look at my picture at 100% you will notice it. I don't know if it is an effect or a defect Best result will be achieved if you can automate the process, so that the camera takes the sequence of exposures on its own. I wasn't able to do it with my k-5 IIs so I did it manually.

The more time you spend in exposures the better and complete circles you will get.
