Description

The Cygnus Loop (W78, or Sharpless 103) is a large supernova remnant (SNR) in the constellation Cygnus, an emission nebula measuring nearly 3° across.

My new wide field setup allowed me to get this famous target in its entirety (or almost) with a two panels mosaïc.
Processing is classical HOO with RGB stars.

Panel 1 :
H : 126x300s
O : 124x300s
RGB : 30x120s each

Panel 2 :
H : 98x300s
O : 128x300s
RGB : 30x120s each
