NGC 55 is an irregular spiral galaxy about 7 Mly away in Sculptor. This area of sky has a relatively low density of stars. The main Sculptor group is around 12Mly away, so this galaxy (and NGC300) are much closer. It is thought to be similar in structure to the Large Magellanic Cloud, though much larger.
This image is 3 hours RGB, shot on a fairly dark night (SQL 21.34 max), although the seeing was not great at about 4", due partly to fairly high winds. The image is about 23% of the full frame area. ASA10N/AAF3; G3-16200; Astrodon filters; DDM85A unguided.
