The print of NGC 1947 here, made from a plate taken in poor
seeing, does not show the intricate detail in the multiple dust lanes
silhouetted against the stellar light of the bulge. At least five
lanes are visible on the original plate; they can be traced outward
(down and to the left in the orientation of the print here) across the
face of the bulge. The pattern suggests that the dust is in a plane
perpendicular to the major axis of the old stellar component, whose
direction on this print is from the lower left to the upper right. If
so, the dust would be in a "polar-ring" orbit.
The outer isophotes of the bulge light are almost circular. The
image of the stellar component can be traced on the original plate
nearly to the left and right borders of the main print.

Re:NGC 1947
For NGC 1947, NGC 5898 and IC 2977 the spectra were too noisy to extract
reliable rotation curves and velocity dispersion profiles. For these
three objects we derived the central velocity dispersion listed in
Table 4.

Re:NGC 1947
NGC 1947: The H{alpha} emission appears to be associated with the
complex of dust lanes visible in the continuum light and clearly seen in
the galaxy-subtracted image. The line emission extends out to r~1 kpc
from the center, and several distinct emission-line knots are also
visible. The gas velocity field has been studied by Mollenhoff (1982),
who estimated the inclination angle of the thin gas and dust disk, giving
rise to the observed parallel dust lane structures, to be about 75^deg^,
The angular momentum vector of the gas component is orthogonal to that of
the stars (Bertola et al. 1992b).

Re:NGC 1947
Dust lane across an otherwise normal elliptical
or S0 intensity distribution.
A second much weaker lane crosses the image further out,
similar to the multiple lanes in NGC 2907,
which is illustrated in Fig. 2 of this reference.
Are these dust lanes in a plane (disk) that is otherwise
invisible and tipped to be nearly edge on to the line of sight?

Re:NGC 1947
SA0p
(Plate 56)
Little elongated, smooth nebulosity, rather similar to
an elliptical galaxy, or to the spheroidal bulge of an
early spiral, cut by two slightly curved lanes of dark
matter on one side of the nucleus.
There is no trace of a spindle or outer spiral structure.
