Ultra-low-surface-brightness dwarf galaxy VF18-71 = VCC 1052 discovered by Sandage & Binggeli (1984). This is an SDSS color image from WIKISKY. The contrast is set extremely high near the sky to show the low-surface-brightness dwarf, but it is set very low at higher surface brightnesses to show some of the internal structure in the trio of galaxies (left to right: NGC 4440, NGC 4436, and NGC 4431) to the south. VCC 1052 is 4 5 north of NGC 4440. This field is in the heart of the Virgo Cluster: M 87 is almost due east (to the left) and NGC 4374 + NGC 4406 are to the northwest (toward the upper right).
