Description

NGC6822, also known as Barnard's Galaxy lies in the constellation at 1.6 million light years distant. NGC 6822 is a barred irregular dwarf galaxy and is part of our local group of galaxy's. It was discovered by E. E. Barnard in 1884 using a small refractor. Within Barnard's Galaxy are several bright reddish HII emission nebula which can be seen in the images above. In the image above the HII region furthest to the NW is known as Hubble 1925 1 (PGC63596 in annotated image) and is often called the Bubble nebula within Barnard's Galaxy. The Ring nebula within Barnards galaxy is right next door to the bubble nebula and looks like a red ring. Its designation is Hubble 1925 III (PGC 63600 in annotated image). Two more bright HII emission regions are named the Hubble V HII complex and Hubble X HII complex (IC1308). A 2015 paper by Veljanoski, et. al. titled "The Globular Cluster System of NGC6822" outlined several globular clusters within the galaxy. All except one were in the field of view and detectable. They are listed and their positions shown on the Annotated image (click on the image for full resolution). There is also a blue/green blob in the upper right of the image. This is the planetary nebula called the "Little Gem Nebula" or NGC 6818. It's a glowing shell of gas ejected from a red giant star late in life. There are few amateur images of it that I could find but a great Hubble telescope shot is available here. It's quite small at 15x20 arc sec in size but looking at the full resolution image you can make out some detail. NGC 6818 was discovered by William Herchel in 1787. There are several faint galaxies throughout the image and listed on the annotated version. Finally, there is some faint dust that can be seen scattered throughout the image which isn't surprising since this is fairly close to the Milky Way in Sagittarius.

The image was shot using 2x2 software binning and the image resolution is 1.28 arc seconds/pixel.
