3. RED LIGHT, GREEN LIGHT
   Inside the faint Flying Bat
   Nebula (Sharpless 2–129) lies
   the even fainter Squid Nebula,
   a tortuous test of imaging
   capability. It was discovered
   in 2011 by the French
   astrophotographer Nicolas
   Outters. In this image, the
   Flying Bat and its HII emission
   are mapped to the red channel;
   the Squid, emitting in OIII, is
   mapped to green and blue. The
   image is made up of 12.3 hours
   of HII data and 24 hours of OIII
   data taken with a combination
   of 2.4- and 2.8-inch telescopes.

4. ALL WOUND UP
   NGC 1350 is a gorgeous spiral
   galaxy in Fornax that glows at
   magnitude 10.5. Both its inner
   and outer arms are tightly
   wound and form rings, making
   it appear like a cosmic eye.

5. ONE NIGHT
   IN EDMONTON
   This spectacular dusk-to-dawn
   moonlit mosaic of Edmonton,
   Alberta, is a meticulous blend
   of vertical slices from
   2,415 images, each made of a
   six-exposure bracket processed
   and rendered in HDR. The
   movement of clouds between
   frames creates a bristle-stroke
   effect — and occasionally blots
   out the Moon from the sky.
