NGC 7417 (Fig. 8, middle).--The images of this galaxy are affected by scattered
light from a bright star just outside the boundaries of the field. There appear
to be two barlike gaseous ovals: a nuclear oval (not visible in Fig. 8) 5" in
radius having an axis ratio of 0.51 and oriented at position angle 0^deg^; and
a second oval 12" in radius having an axis ratio of about 0.63 and a position
angle of 35^deg^ (this one is visible in the right middle panel of Fig. 8). The
primary stellar bar visible in the continuum image is oriented at a position
angle of 43^deg^; thus, both apparent gaseous ovals are misaligned with the
stellar bar. Both ovals lead the primary bar if the outer arms are trailing.
The nuclear oval has no stellar counterpart. The galaxy has an inner ring and a
bright outer pseudoring. A few discrete H II regions are associated with the
inner ring. Many more are in the outer arms. Owing to the effects of the
scattered light, no parameters for this galaxy are tabulated here.
