Steve's Notes

===== NGC 4503 24" (6/4/16): bright, large, elongated nearly 5:2 N-S, ~1.8'x0.7'. Sharply concentrated with a very large, very bright elonagated core that increases to an even brighter nucleus and stellar peak at the center. The halo gradually fades out but the ratio of major to minor axis is higher in the halo than the core. IC 3470 is 6.7' NE and IC 3483 (the third member of Zwicky's Triplet, along with IC 3481 and 3481A) is 19' NE. 17.5" (4/25/87): fairly bright, fairly small, elongated ~N-S, very bright core, stellar nucleus.
