11. NGC 3705 (mag. 11.1, s.b. 13.3). To pick up this galaxy you need to make a side excursion south past Iota (i) Leonis. (Iota is a bright, slightly greenish white binary, magnitudes 4.0 and 6.7, with a current separation of only 1.6" in position angle 121°; try your highest power.) The galaxy, however, is worth the trip. In the 6-inch it was easy at first sight, small and round with hints of elongation, in a nice, starry field. It is the brightest in a group of much fainter galaxies that may be visible with large apertures under good skies.
12. NGC 3489 is back on our main line. With a magnitude of 10.3 and a favorable surface brightness of 12.2, it was plain as day at first glance a glow with a very sharp stellar nucleus, and, I thought, signs of east-west elongation.
13. Struve 1496 (S1496) is a nice double star, moderately wide with very unequal components, magnitudes 8 and 10, 20" apart. The faint star is in position angle 352°, almost due north of the primary. Their colors seemed white and gray-brown.
14. h2547 is a fainter double, a pair of nearly equal 11th-magnitude stars 27" apart in position angle 65°. They are both G stars, possibly dwarfs like the Sun.
15. NGC 3412 (mag. 10.5, s.b. 12.4) was also seen at first glance. The faint galaxies seem to be getting easier now! This one appeared quite small and condensed with a bright nuclear area; a nice little grayish glow.
16. NGC 3377 and 3367 (mags. 10.4 and 11.5, s.b. 12.8 and 12.9). NGC 3377 was also visible at first glance; it displayed a bright, very stellar nucleus in a larger surrounding glow.
I didn't see NGC 3367 at first. But with a lot of effort I finally picked it up, after breathing deeply and shielding all extraneous light from around the eyepiece. It was a large, diffuse glow with little or no central condensation.
