Steve's Notes

===== NGC 7647 24" (9/2/16): fairly faint, fairly small, slightly elongated, 30"x25", gradually increases to the center. With averted vision a very low surface brightness outer halo was detectable. NGC 7647 is the brightest galaxy (cD) in AGC 2589, a richness class 0 cluster at a distance of ~560 million l.y. Surrounding NGC 7647 is a large number of very faint galaxies with PGC 71331 (2.1' N), PGC 71337 (2.2' NE), PGC 71326 (1.7' S) and PGC 71317 (2.3' WSW), forming a small rectangle around the bright elliptical. Additionally, I picked up PGC 71320 6.2' NNW, PGC 71324 8.4' N and CGCG 454-062 8.1' SSW. These 7 additional members were very faint or extremely faint and generally 0.2' in size. 17.5" (9/26/92): extremely faint, very small, slightly elongated N-S. A mag 13 star is 1.5' ENE. Appears unusually faint for 15.2z due to low surface brightness. Note: There is no mag 13.5 star to the ENE, so my observation may refer to another galaxy.
