Description

******************************************************************************

Photographed at Algonquin Provincial Park, Ontario, Canada

* Temperature -4 degrees C.

Our home galaxy crosses the summer sky in this super wide-angle view, running from the constellation Cepheus at left, through Cygnus with its distinctive red-pink ionized hydrogen gas clouds, and on through Aquila and Scutum at the right side.

The three bright stars of the "Summer Triangle" (that is, summer in the northern hemisphere, but winter in the south!) can be seen at top left of centre (Vega), centre left (Deneb), and right of and below centre (Altair).

During one of the four subframes that comprise this image, a meteor flashed across the sky at lower right, probably at an altitude of about 60 km.
