First light for the Autumn season 2018, Filaments of the Western Cygnus
After a long mandatory Summer pause, due to high latitude, I managed to have my first light for this season! My first target locates in Western part of the Cygnus nebula complex. This area is not commonly imaged due to close proximity of more famous and brighter target in Cygnus.
As usually, this single image is a start of the longer imaging projet. My purpose is to make a four panel mosaic out of this area.
