The arm pattern in NGC 4947 is of the
grand design type. Two principal arms exist,
beginning at the center as dust lanes and becoming
luminous at the edge of the inner disk. The
HII regions are numerous.
The redshift is v_o = 2222 km/s.
= IC 3974
Overexposed center, pretty faint bar, bright (r): 0.65 x 0.4, very patchy
arms with several pretty bright knots. 5 min error in IC RA.
=ESO 382- G 05
5 minutes error in IC RA
High-surface-brightness thin arms that are lumpy but
unresolved into HII regions at this scale.
Small but bright nucleus with no central bulge.
Small, bright nucleus. (r): 0.85 arcmin x 0.5 arcmin.
