Description

This is a 16-frame mosaic. Each frame has an exposure time of slightly more than half hour. The original image has 338 mega pixels. The one uploaded here is 0.4x reduced.

The standard (original) version is slightly cropped, so the Milky Way is at the frame center. There are some interesting clouds outside the southern edge of the image. Rev.B is an uncropped and contrast-enhanced version, to show those clouds.

A slightly larger (0.66x) uncropped version can be viewed from GigaPan:
