M81 and M82 are magnitude 7.0 and 8.6, respectively, galaxies in Ursa Major. M81 is called Bode's Nebula because it was discovered by Johan Elert Bode at a time when it wasn't known that these objects are galaxies outside our own galaxy. M82 is called the Cigar Galaxy because of its apparent tapered cigar shape.
Taken under breezy conditions, moderate to poor seeing.
