   Today and every Saturday Earth Science Picture of the Day invites you
   to rediscover favorites from the past. Saturday posts feature an EPOD
   that was chosen by viewers like you in our monthly Viewers' Choice
   polls. Join us as we look back at these intriguing and captivating
   images.
   Photographer:  Greg Parker
   Summary Authors:  Greg Parker;  Jim Foster

    October 2014 Viewer's Choice Shown above in this extreme wide-field
   view (10 x 7 degrees) of the summer sky is the central region of the
   constellation of  Aquila the Eagle. The bright star at left center
   is  Altair, the brightest star in  Aquila.  Alshain is below
   Altair and  Tarazed above it -- the second and third brightest stars
   in Aquila, respectively. The very dark portion of the sky, just to the
   right of Tarazed, is known as  Barnard's "E." It consists of two
    dark nebulae (dust and gas clouds) approximately  2,000 light
   years distant.
   Altair also forms the southernmost star in  the Summer Triangle.
   This conspicuous  Isosceles triangle is still visible during the
   Northern Hemisphere's  autumn season, in the southwestern sky, soon
   after sunset.
   Photo Details: Canon 5D MkII camera; DSLR and 200 mm lens were
   piggy-backed on a Celestron Nexstar 11 GPS telescope for tracking.
   Images were taken at ISO 400 and f/4 with a Hutech IDAS light pollution
   filter fitted to the front of the 200 mm lens. Exposures were 4 minutes
   with a total of 24 exposures (subs). RAW data-files expertly processed
   by Noel Carboni, in Florida, U.S.A.
