NGC 2903 is a large and bright galaxy in Leo, about 1.5 degrees south of lambda leonis. It is a multi-armed spiral, tilted at a substancial angle. It is a very good object for small telescopes, appearing as a large oval patch of light in an 8" telescope. In a 10", the spiral structure is visible.
The galaxy visible at the top (east) is the 11.9 magnitude spiral PGC 2916.
