Filaments of Cygnus
I have shot the constellation Cygnus for many years with different instruments. Due to that, I'm able to build mosaic images from my overlapping material. This time I made a four panel mosaic showing remains of the two exploded stars in Western Cygnus.
Bluish hues at left part of the panoramic image are from supernova remnant W63. At most right lays the planetary nebula PM 1-320.

This four panel panoramic mosaic has a total exposure time of about 35 hours.
Each panel is shot with Celestron Edge 11" reflecting telescope (with a 0.7 focal reducer), Apogee Alta U16 cooled astrocamera and Astrodon narrowband filter set (5nm H-alpha, 3nm S-II and 3nm O-III)

Image is in Natural color palette from the emission of ionized elements, R=Hydrogen + Sulphur, G=Oxygen and B=Oxygen + 10% Hydrogen to compensate the missing H-beta emission.
H-alpha alone

This photo shows the light from an ionized hydrogen (H-alpha emission) alone

Image is in mapped colours, from the emission of ionized elements, R=Sulphur, G=Hydrogen and B=Oxygen. This mosaic image of four individual panels covers about four degrees of sky vertically.
