Sh2 173 Emission Nebula in Cassiopeia.
Acquisition with DSO, my remote observatory located in Manciano.
This nebula which I found not so bright it took me a bit of work because the nebula is surrounded by a rich field of stars. I have so tried to keep the color of the stars while not giving the weaker parts to issue. Of course I have also reduced our impact of the stars to highlight a little better the structure of the nebula. It seems that the nebula is about 8800 light years trovia in the Perseus arm .... well, far enough away!
