Barnard 312 (B312) is a large, prominent dark nebula in the constellation Scutum, located roughly 2,000 light-years away within the rich star fields of the Milky Way. Positioned near the Eagle Nebula (M16) and Omega Nebula (M17), it appears as a stark, mushroom shaped silhouette against a dense, bright backdrop of stars.
Dark nebulae like B312 are dense clouds of interstellar dust and gas that block visible light from objects behind them, creating striking void like shapes against illuminated star fields. First catalogued by Edward Emerson Barnard in his 1919 photographic survey of dark nebulae, B312 is one of the most visually dramatic entries in the catalogue.
Imaged with an Orion 8 inch Newtonian reflector and Canon T3i (full spectrum modified), 46x180s exposures captured in N.I.N.A 3.1 and stacked in Siril 1.4.0.
