Perhaps this post belongs in the science forum but the WLM dwarf galaxy has been intensely studied by the professionals.
The 3.5M ESO image of the galaxy is obscene given how deep the image is with ridiculously small exposures , 2 X 45 minute mosaic
with a near-IR filter in 0.9 arcsec seeing conditions!!
