Active region in the Pelican Nebula (IC 5070) in H-alpha, H-beta, O-III, N-II, and S-II with multiband filters.
The Netherlands in Bortle 7/8
My first *real* DSO capture. Before this, captures of maybe 1 hour. This one is 5:20 hours in total.
And still on f/10 without guiding
This is a part of the Pelican Nebula with star formation. It includes several Herbig-Haro (HH) objects of which HH 555 is the most prominent one.
An HH-object is a jet of particles and gas ejecting from forming stars. This with several hundreds of kilometres per hour.
In the top of the large, vertical dust pillar is an invisible forming star. But the jets are visible, in this case the small horizontal line.
Other HH-objects are there but not with such prominent outbursts.
