Re:NGC 7421
Patchy red (dust) lanes down to nucleus

Re:NGC 7421
Nuclear dust lanes. The profile is fitted by an R^1/4^ law with
R_e_ =20.2" and V_F606W_ = 12.6. This fit clearly includes the bar
component, and it has therefore been omitted from our analysis.

SBbc(rs)II-III

Aug 17/18, 1979
103aO + GG385

One of the two principal arms that can be
traced begins about a quarter turn downstream
from one of the ends of the bar. The opposite arm
seems to begin at the end of the other side of the
bar.
These arms fragment almost immediately
into a semi-chaotic filamentary arm structure;
hence the late luminosity classification is
required.
The redshift is v_o = 1838 km/s. The largest
HII region may resolve at the 2" level.
