Description: A quite faint but beautiful galaxy, (almost) edge-
on. Size 6.5'x1', PA 170°. Quite strongly concentrated but no
real core. The N part of the disk is somewhat brighter. There is
a non-stellar knot in the N part near the vF star projected
against the disk. On the E side of the center there is a star
(mag. 13). A thin brighter filament follows the edge of the
galaxy towards SSE from the star. There are a few eF stellar
brightenings in the outer third of the S part.
