t MILK Y WAY OVER OWENS VALLEY

Mike Oria
Caltech astronomers picked an isolated area just north of
Big Pine, California, to get a "quiet" environment for the
Owens Valley Radio Observatory and its big 40-meter dish.
But it's also an awesomely dark place for stargazing.
DETAILS: Pentax 645Z medium-format DSLR camera at ISO
1600 and 25-mm lens. Exposure: 25 seconds.
q TRIANGULUM'S PINWHEEL

David Collings
Messier 33 is the third "anchor" in our Local Group of galaxies and the second-closest spiral (after M31). Its sweeping
arms, though not as distinct as those of other spiral galaxies, bristle with intense bursts of star formation.
DETAILS: Celestron EdgeHD 11 aplanatic Schmidt-Cassegrain
telescope with Hyperstar and Starlight Xpress Trius-SX814C
color CCD camera. Total exposure: 72 minutes.
q q STALKING THE HERON

Bruce Waddington
Arp 84, aptly named the Heron, consists of the nearly face-on
spiral NGC 5395 and its entangled companion, NGC 5394.
Both galaxies are tucked in southeastern Canes Venatici.
DETAILS: PlaneWave Instruments CDK12.5 astrograph, QSI
640ws CCD camera, and LRGB filters. Total exposure: 9.8 hours.
