Simeis 57 Propeller Nebula, 14×4 min

 

With my usual setup, the N 150/750, Baader MPCC Mark III, Canon 1100D mod, HEQ5, autoguided, I imaged the Propeller Nebula from the Curmături cabin. I acquired 14×4 min ISO 1600 light that turned out to be usable, the rest of the frames suffering from guiding errors. The object itself is close to γ Cyg, Sadr, and it is part of the huge nebulous complex in the area.
