Supernova SN 2017eaw in a galaxy NGC 6946 (Fireworks Galaxy) is still shining as billion suns (the supernova is marked by green dashes -- see the second picture beneath). The galaxy is distanced from us at approximately 22,000,000 light years.
Most of the stars in the picture (except the supernova) belongs to our Milky Way. An open star cluster NGC 6939 is visible in the upper right corner (a distance to it is about 4,000 light years).
A picture was taken in the night 27-28 of May 2017 from Kyiv.
There were 91 light frames in total @ Tv=30s (total exposure 45.5 min) plus 21 darks, 21 biases, and 10 flats.
This is a combo image: synthetic L-channel overlapped by RGB image.
