*This image was started the night after my cooling fan on the ST-8 had stopped working ... -10c is the best temperature I could maintain. When I got a new fan from SBIG about a week later, I had already taken most of this sequence. On May first I re-imaged the last 12 images from the sequence from the night of 04/13 at -15c.
The small galaxy to the SSW of NGC 4565 is NGC 4562 (2.5'x0.7', mag 14.0p, Cl: SB(s)dm: sp).

NGC 4565 = UGC 07772 = MCG +04-30-006 = CGCG 129-010 = FGC 1471 = PGC 42038 12 36 20.6 +25 59 15 V = 9.6; Size 15.8x2.1; SB = 13.3; PA = 136d 17.5": bright, very large, edge-on 12:1 NW-SE, dimensions approximately 16'x1.5'. A beautiful dark lane is visible continuously with direct vision along most of major axis although more prominent in the center. The galaxy is split asymmetrically by the dust lane with the southern half both larger and brighter. There is subtle scalloped structure visible along the dust lane. Contains a small bright core with a stellar nucleus at the south edge of the lane. A mag 13.5 star is 1.6' NE of the center. 13": a faint dark lane splits central bulge into two unequal parts. The nucleus is brightest to the south of the lane. The northern section beyond the lane is fainter. - by Steve GottliebContemporary Visual Observation(s) for NGC 4562
