The Soul of the Soul (Dobashi 3919) in Hα-SII/OIII/OIII+rgb


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...
