1. SOUTH OF THE BORDER
   The stars of the constellation Crux
   the Southern Cross glow brightly
   at the upper left of this image. Its
   bottommost star, Acrux (Alpha [α]
   Crucis) lies next to an intensely dark
   nebula called the Coalsack. On the
   right, the spectacular Carina Nebula
   (NGC 3372) glows intensely red.

2. CAMERA SHY
   Most amateurs consider M89 to be
   just another boring elliptical galaxy,
   so they don’t target it. As this image
   proves, however, it’s anything but
   that. The photographer captured and
   combined an incredible 16 hours of
   exposures. Some of the outer shell
   seen here is newly discovered.
