About this Image

This deep exposure is showing one fifth square degree of our night sky in the Constellation Bootes.
The field is dominated by the ringed barred SBab galaxy NGC 5945 left of the center at a distance of 250 million light years.
Below is the distorted and dusty galaxy NGC 5943 is showing signs of a recent collision with another galaxy resulting in extended star streams to both sides of the galaxy.
To the right border an interacting galaxy pair (NGC 5934 and NGC 5935) also is showing extended star halos.
Find below a stretched image to show the faint streams in 22/35 % size.
