Feb 3/4, 1978
103aO + GG385
The spiral pattern can be inferred for
NGC 1406 by the curvature of the two dust lanes near
the outer edge of the disk on both sides of the
The redshift is v_o = 998 km/s.
Overexposed center with dust lane and pretty smooth arms.
Nearly on edge.
Two intense dust lanes on the insides
of the two main (massive) arms.
No useful resolution into stars or HII regions.
