Outside of this is an oblong of somewhat fainter matter 20" X 13", from the ends of
which extend two fainter ansae in p. a. 97–277°. From the north and south sides
of the central oblong extend two longer ansae in 167–347°, showing a ring ...

This outer portion likewise is fainter at the ends of the major axis, and shows
brighter streaks at the east and west edges. Relatively faint; the inner ring just
shows in 5" on S27. Rel. Exp. 15. N.G.C. 7662; 23° 21m 1; +41° 59' Exposures 1"

This is quite irregular, and one end of the apparent major axis is considerably
fainter. 1514 (7). Of very irregular structure; the dark lane is displaced to one side
of the (probable) major axis. 2438 (18). A very irregular ring, nearly round.
