Steve's Notes

===== NGC 1530 48" (10/29/16): at 488x; bright showpiece barred spiral! A relatively wide, very prominent bar extends WNW-ENE [PA 122¡] and is steeply inclined to the orientation of the core. The bright core, centered on the bar, is elongated N-S and contains a very bright round nucleus that increases to the center. Two relatively bright and very distinctive thin spiral arms extend from the ends of the bar. The western arm is brightest in a region near the root, where it attaches to the bar and contains a small knot. The spiral arm is mostly visible extending north ~1.5' and only slightly curving east. A short, low contrast section of the arm extends south of the bar. A second long thin arm nearly perpendicular to the bar extends south a similar 1.5'. It is also brightest at its origin on the east end of the bar. The arm only extends a short distance and blends into the low surface brightness glow of the halo on the north side. From north to south tips of the arms is at least 3'. Two mag 15 stars are at the NE edge and a collinear mag 15.5 star is off the NW arm. 24" (12/28/13): at 200x, appeared fairly bright, large, elongated nearly 3:2 N-S, ~3.5'x2.2'. Contains a large, brighter circular core within a very large, elongated halo. A low contrast, thin spiral arm is attached on the west side of the core and sweeps north at the edge of the halo and a similar enhancement is visible on the east side extending due south. Two mag 15 stars [22" separation] are superimposed on the NE side [1.1' from center] and a mag 12.8 star lies 2.5' N. 13.1" (1/18/85): fairly faint, fairly large, very diffuse, almost round, gradual weak concentration, no nucleus.
