Description

The region around the stars Sadr and Deneb in the constellation Cygnus (Swan) is rich in emission nebulas and therefore a great target for bright nights -with narrowband filters.

The image shows famous Nebulas like North America Nebula (NGC 7000), Pelican Nebula (IC 5070) the Veil Nebula supernova rest complex, the Propeller Nebula (Simeis 57) and the Crescent Nebula (NGC 6888) in an overview image.

This is an RGB-HOO combination. Data acquired with Pentax SMC DFA 2.8/50mm and ASI2600mm pro.
