Shoot the stars

DragonflyOkay, let’s say you’ve got a need to look deep into the universe and, let’s say, your local observatory just doesn’t cut it or is booked solid for the next several decades. What do you do?

How about buying 10 Canon 400 mm lenses, putting them into a special mount, and voila, you can now see even extremely faint galaxy structure.

That’s what astronomers at the University of Toronto did, creating Dragonfly (they say it resembles a dragonfly’s compound eye) for ultra-low surface brightness astronomy at visible wavelengths.

Images have shown Dragonfly is at least ten times more efficient than its nearest rival and will be able to detect faint structures predicted by current merger models.
