About this image

Friday night meeting of local astronomy club (Sous Les Etoiles D'Albret).  Nine scopes lined up.  Beautiful clear skies with moon rising around 11:25 local time. Cygnus right overhead.  Decided to use H-alpha filter to avoid moonlight and capture wide-filed view of the Milky Way.  Images calibrated, aligned, stacked and processed in Affinity Photo.  Rather flat tones due to low light capture.
