Notes:

The primary is a semi-regular variable.
The stars have a small difference in proper motion. Also, may be optical because
Hipparcos gives different distances (820 and 720 light years).
Observations:
C8 at 104x.

Notes:
This is a Seyfert Galaxy.

Observations:
C8 at 206x. No discernible nucleus. It has an NE-SW axis and lies 3 min W of a 9m
star. Another 9m star lies 3 min farther E. The bright star (7.6m) 7 min E is SAO 62291.
C11 at 193x. The C11 shows a brighter middle in an oval smudge.

Observations:
C11 at 339x. Very difficult streak that lies behind two fairly bright foreground stars.
(These make it all the more difficult to see.) I had to use tube movement to confirm it
was there. At times (due probably to variable transparency), the galaxy showed some
mottling.
C11 at 98x. Good field; very faint blip just N of an 11m star. It very gradually
brightens toward the center. Small halo, oblong shape.
