North is left. Sh 2-71 is the bright planetary nebula at the top right corner. Sh 2-72 is a hydrogen emission nebula, the one to the botton right, obviously. Narrow band picture, therefore processed in false color using a modified "Hubble palette" SHO.
Started to take subframes one year ago, in October 2017, and just finished this weekend. A total of 141 subframes of ten minutes each. That is 23.5 hours of exposure.
