MIlky Way and airglow

 These images of the Milky Way rising over the western ridgeline of Snowshoe Mt were obtained in the late evening of 01 June 22 in Creede.  The camera was riding on a motorized Orion EQ-1 equatorial mount.  There are strong bands of green and red airglow visible in these exposures.  The sky was reasonably dark, with sqml=21.45.

In this image the constellation Scorpius is on the right and the Milky Way Core is left of center.

The next evening the sky was darker (sqml=21.5) and the airglow greatly diminished.  I switched to a wider-angle lens:
