Both were very faint, hard to detect visually. M82 was fainter than M81. M81 was close enough to another star I at first mistook it for a double star with the nebulosity sometimes seen on double stars. I drew M81 before finding M82. Both appeared to be faint elliptical smudges with star-like nuclei. In sketch below, view is centered on HIP48803 (whose coordinates are given above). At 22:15, a satellite passed through the field of view (shown). To find this field in binoculars, aim at the top of the bear's nose (23 UMa, mag. 3.62) and move outward (North) along a line perpendicular to the line formed from the other two stars of the bear's nose (Upsilon, mag. 3.75, and Omicron, mag. 3.34). Pass a quadralateral of stars (a bright triangle means you are too far west), and arrive at a pentagon that looks vaguely like a smiley face. Continue on the line to find a boomerang shape with west end at 24 UMa, mag. 4.53, and the galaxies are to the east.

Oh be a fine girl--kiss me!
