Steve's Notes

===== NGC 598 17.5" (11/1/86): bright, very large, elongated 3:2 SSW-NNE, weakly concentrated irregular halo, rises suddenly to a small bright core. Two prominent spiral arms form an "S-pattern" with an irregular surface brightness. At least a dozen HII regions or clusters are resolved (see the numerous IC listings). Overall, the entire galaxy is very mottled and the outer extent is difficult to define. 13.1" (8/23/84): two prominent spiral arms distinctly visible. 8" (10/4/80): the bright central region is slightly grain with the halo showing some indication of spiral arms. The edge of the arms were glimpsed with averted vision. Naked-eye (several times): just glimpsed in very dark skies, perhaps visible 25% of the time in best conditions.
