Sharpless 2-264 is a nebula with emission and a molecular cloud surrounding the star Lambda Orionis. Its nickname, the Angelfish Nebula, is due to its profile in shorter exposures, though it appears rounder in this deeper exposure. The imager used a 135mm f/2 lens and monochrome camera with a dual-band Hα/OIII filter and RGB filters, taking 2 hours of exposure.
