A pair of globular clusters in the constellation Sagittarius. At the top right is M28, on the left is NGC 6638. In the center is the fairly bright orange giant λ Sagittarii, or Kaus Borealis. These objects have a declination of about -25 degrees, and during the capture, they were about 10 degrees above the horizon.
Balcony in Kharkiv, red zone light pollution.
