Description

Image taken in a single moonless night. Notwithstanding the favorable weather forecast, it was cloudy till 1 a.m. with residual clouds for the rest of the night. I decided to image anyway, and to elaborate the few sub-exposures with decent signal to noise ratio.

NGC 5395 and NGC 5394 are known collectively as the Heron Galaxy thanks to their gravitationally distorted appearance that originates heron's long neck and beak in the space, being NGC5395 the bird's head. NGC 5395 is included in the Atlas of Peculiar Galaxies as Arp 84 in the category "Spiral galaxies with large high surface brightness companions".
NGC 5395 is located at a distance of 160 million light years, receding away from the earth at about 3500 kilometers per second, in the constellation Canes Venatici. It was discovered by William Herschel on May 16, 1787. It has a diameter of around 140,000 light-years, and is a Seyfert 2 galaxy.
NGC 5394 is the smaller galaxy, with a diameter of around 90 thousand light years.
