Helix Nebula - NGC7293

One of the largest planetary nebulae, the "Helix Nebula." Its angular size is nearly half that of the Moon's disk, yet it has low surface brightness and is observed low above the horizon at mid-northern latitudes. During imaging, its altitude was about 15 degrees, just above a double streetlight: https://deepskyhosting.com/ivFNOMk Five sessions in the second half of October 2019—two with the Moon present, two with light haze, and all with streetlights on. Balcony in Kharkiv, red zone light pollution.
