Steve's Notes

===== NGC 2535 48" (4/2/11): this is the prominent member of a striking interacting pair (Arp 82) with NGC 2536 1.8' SSE. At 375x appeared bright, fairly large, elongated 5:3 SW-NE, ~1.6'x0.9' (including arms). Contains a relatively large, bright core spanning ~40"x30" and punctuated by a very bright, stellar nucleus. Attached at the west side of the core is a graceful spiral arm that curves clockwise towards the south-southeast in the direction of NGC 2536. The arm fades towards the south-southeast end and increased in length with averted vision though it did not reach the smaller companion. A second arm is attached on the east side and shoots north, though it's only 2/3 the length of the interacting arm. A string (1.4' length) of three mag 12-13 stars is off the west side of the galaxy. 17.5" (2/20/88): fairly faint, fairly small, slightly elongated SW-NE, weak concentration. Forms a close pair with NGC 2536 1.8' SSE (Arp 82). Located just following a line of three mag 12 stars 1.6' WSW, 1.2' W and 0.9' NW of center. 13" (1/18/85): faint, small, round, diffuse, even surface brightness. Located 22' SSE of a mag 6 star.
