The Pleiades star cluster, Messier 45, amid the faint and dusty nebulosity that surrounds it. The stars of the Pleiades are passing through the dust clouds in Taurus and are lighting them up as examples of reflection nebulas.

Flat-fielded in PixInsight using T-shirt flats, and developed in Photoshop. Taken from home January 27, 2020.
