Always I planned to adquiere as much data as possible of the center of this object.
Now after 80 hours of integration time I am really happy with the results.

A lot of details on LBN673 and a powerful Dobashi 3919 just on the center.

All these details belong to the main object Sh2-199 called Soul Nebula, mainly is a large emission nebula in the constellation Cassiopeia approximately 7,500 light years distance.

My main project is to add more teselas to this mosaic, I will continue next year…
