    NGC 55 maybe a member of the loosely associated Sculptor galaxy group, a close neighbor of our own “Local Group.” NGC 55 lies only about 6.5M light-years away. It is gravitationally bound to NGC 300, also in my Astrobin collection.

    This nearly edge-on view shows dust bands and HII red clouds, and the blue from many young hot stars--NGC 55, apparently, has had a long history of high-rate star production. It is thought to be a barred galaxy, resembling the Large Magellanic Cloud. The distorted shape has be attributed to an abundance of super-novae explosions and extensive strong stellar winds.

    Annotated with DSOs from the HyperLeda data base. I used an Excel spreadsheet that I wrote to extract the data from a download and to format it for PixInsight's "AnnotateImage" script. The spreadsheet is available here: https://groups.io/g/Astro-ImagersSidebar/topic/image_annotation_from/68690699?p=,,,20,0,0,0::recentpostdate%2Fsticky,,,20,2,0,68690699 (feel free to join that group too!) -
