The shooting night accommodated another DS object in addition to the open constellation NGC 6709 , and the constellation was the same. This time it was an annoyingly neglected planetary nebula. One edge of the object turned out to be much dimmer than the others. The color scheme was reminiscent of Lyyra's tire mist.
