M82, also known as the Cigar Galaxy due to its long, narrow profile when viewed from Earth, is a vibrant starburst galaxy located roughly 12 million light-years away in the constellation Ursa Major. It is celebrated as a cosmic factory, churning out new stars at a rate nearly ten times faster than our own Milky Way. This intense bursts of star formation is fueled by a close gravitational encounter with its neighbor, the spiral galaxy M81, which compressed gas clouds deep within M82's core. As a consequence of this furious stellar birthrate and subsequent supernova explosions, a powerful "superwind" drives massive, glowing plumes of hot hydrogen gas and dust thousands of light-years out into space, sculpted into dramatic red filaments that blast perpendicular to the galaxy's main disk.
This HaLRGB image was captured in a Queen Creek (Arizona) Bortle 7/8 backyard using a Skywatcher Esprit 150ED telescope. The telescope is mounted on a 10Micron GM2000 HPS II mount. The camera is a ZWO ASI 2600MM Pro using Antlia VPRO LRGB and 3nm HA filters. It was captured over 48 nights (2022-12-20 to 2025-02-26). The images were captured using NINA and stacked/processed in PixInsight.
