The Dragonfly Array consists of two telescope mounts, each carrying 24 ultra high contrast lenses. These off-the-shelf Canon lenses use new nano-fabricated coatings with sub-wavelength structure on the optical glass, which has unprecedented performance in reducing stray light and reflections.

On the back of each of these 48 lenses is an SBIG STT-8300M camera.

The purpose of the array is to search out ultra low contrast objects, which have been overlooked by more conventional instrumentation.  Recently the discovery of Dragonfly 44 was reported.  This newly discovered galaxy is 99.99% dark matter.

This discovery opens an important new window on dark matter, and has important implications for theorists seeking to understand Cold Dark Matter and how galaxies were assembled following the Big Bang.
