The imaging of this object started two years ago.
After a total of 30 hr luminance, the law of diminishing returns suggests that further imaging will not add much to this extremely faint object.

As a comparison here is an image of the dwarf taken by combined exposures from the 2.2 meter MPG/ESO and the Victor M. Blanco 4-meter telescopes in Chile.
