NGC/IC Project Restoration Effort

===== NGC 4490. See NGC 4485.

===== NGC 4490 18" (6/7/08): I viewed this interesting pair in my 15x50 IS binoculars (just a faint blur), 18" Starmaster (disturbed arm on the WNW end extending towards NGC 4490 easily visible) and the 33.4" f/5 (internal structure visible). 18" (6/13/07): very bright, large, elongated 5:2 WNW-ESE, ~5'x2', with a very bright oval core, ~45"x30". The surface brightness is irregular or mottled but most interesting is a small extension or arm that juts out of the WNW end and appears to bend or hook north towards the companion NGC 4485. There appears to be a smaller counterpart at the ESE end that slightly protrudes from the main body. With averted vision, the galaxy grows wider and appears ~5'x2.5'. Located 39' NW of mag 4.3 Beta CVn. Member of the CVn II Group (brightest member M106). 18" (6/4/05): very bright, large, elongated 2:1 NW-SE, contains a large, bright core. At the northwest end a faint arm appears to emerge hooking sharply to the north for 1' towards NGC 4485. At the southeast end, there appears to be slight extension without much curvature near a 16th magnitude star. The central region is weakly concentrated to the center. Overall, the galaxy has a mottled, slightly splotchy appearance as if was dusty or knotty with HII regions. Located 40' NW of 4.2-magnitude Beta Canum Venaticorum. 13.1" (2/16/85): very bright, large, striking, elongated 2:1 NW-SE, 6'x3', large bright core is elongated and grainy. A very faint arm extends from the NW end in the direction of NGC 4485 3.6' NNW. A small extension (arm) at the SE end is suspected. Similar view and sketch made on 2/23/85. On 4/12/86, just a hint of curvature was noted towards NGC 4485.
