Description

This is a first for me...just came across while looking for a target in the area. I've heard of it before, but never seen anything on it.

According to the Hitchikers Guide, Barnard's Galaxy is a barred irregular galaxy approximately 1.6 million light-years away in the constellation Sagittarius. Part of the Local Group of galaxies, it was discovered by E. E. Barnard in 1884 (hence its name), with a six-inch refractor telescope. It is one of the closer galaxies to the Milky Way, but lies just outside its virial radius (whatver that is!)  It is similar in structure and composition to the Small Magellanic Cloud. It is about 7,000 light-years in diameter.

Wasn't hopeful of much of interest with first images in LRGB, but tried some Ha and OIII and picked up some interesting nebulosity.

Stacked in APP and recombined in Startools and processed there and then into PS for final processing.
