IC1805 is a large emission nebulae in Cassiopeia that I captured here with narrowband filters, a monochrome camera, and a telescope with a focal length of 464mm. It was all shot from my light polluted backyard in Somerville, MA. Mapped color in the Hubble Palette (SHO->RGB).

Processing in PixInsight and Photoshop.
