I found some forgotten raw material I collected during the summer. Tech details show the frames were more like tests than a serious attempt at photographing this object. Nevertheless it was worth the shot.
NGC 6888, also known to amateurs as Caldwell 27, the Crescent nebula is a faint, 10m deep sky object in Cygnus, near the well known Sadr (γ Cygni) region. The nebula is blown by the Wolf-Rayet star WR 136 (HD 192163).
