| Notes: |
The group is named after M 105 (centered, the large featureless E1 galaxy is the westernmost object), the elongated SB(s)o-: NGC 3384 next largest to the east (left), and finally the little spiral NGC 3389 SA(s)c. This is a reshoot of a 260 minute red-filtered image from 05/29/30/31/2006 ... didn't gain much from doubling the exposure. This image was taken with no moon, but hazy sky conditions |
