NGC 4438
24" (4/28/14 and 5/29/14): very bright, very large, very elongated 5:2 or 3:1 SSW-NNE, 3.0'x1.0'. Contains a large, bright elongated core that increases to a very small, very bright nucleus. With averted vision, much fainter irregular extensions (with an uneven surface brightness) significantly increase the outer diameter. The southwest "plume" is not aligned with the major axis of the galaxy and spreads further towards the west.
18" (6/12/10): bright, large, elongated 5:2 SSW-NNE, 2.4'x1.0'. Contains a bright, elongated core that increases to a small, very brighter, rounder nucleus. The outer halo appears warped with very faint extensions that increase the overall size to nearly 5'x1.5'. The southwest extension is more noticeable and appears to bend or curve to the southwest (counterclockwise). The NNE extension is extremely faint and slightly offset to the axis of the core. This highly disrupted galaxy forms an excellent pair with NGC 4435 4.3' NNW along Markarian's Chain.
17.5" (4/25/87): bright, elongated 5:2 SSW-NNE, small bright core. Forms a striking pair with NGC 4435 4.5' NNW. The core is not as large or bright as NGC 4435. Located in the center of the Virgo cluster 23' E of M86.
13.1" (5/14/83): bright, bright core, larger but more diffuse than NGC 4435.
