IC 4895 (NGC 6822): an irregular galaxy in Sagittarius
For many “young” stargazers, the splendid constellation of Sagittarius host a plethora of open and globular clusters, as well as splendid gaseous clouds, because of the rich Milky Way making that part of the sky so generous of wonders.
But there is something more, well beyond our own Island. IC 4895 (NGC 6822) is an irregular galaxy, placed at about 1.6 millions of light years, and is part of the so-called Local Group. It was the first galaxy out of the Milky way system where Edwin Hubble discovered Cepheids and measured them, finding IC 4895 was a galaxy well outside the Milky Way.
From the northern hemisphere, this galaxy is always low above the horizon, so it is impossible to capture its amazing beauty and richness at their best, but IC 4895 still shows its stars and main features from there.
Above is an image coming from the average of 8, 300-seconds exposures, remotely taken with the 17″ robotic unit part of the Virtual Telescope. It is amazing to note how rich is that part of the sky, with plenty of stars from our Milky Way and IC 4895 showing itself well resolved.
