Glass Butte OR Nightscape

Caption: Here's another Milky Way panorama, with this one from Glass Butte, Oregon (about 75 miles SE of Bend).
That's the view to the NE along the bottom, and the view to the SW at the top. The photo is a composite of 12 images, each a 4 minute exposure, ISO 1600, f4.5 on a Canon 40D with a 10mm-22mm lens. The camera tracks with the Earth's rotation on a SkyMemo mount.
That's Jupiter shining brightest at the top, Altair below Jupiter just a ways, then Vega down and to the left. That white smudge to the right and up about one third of the image is the Andromeda Galaxy. Over to the left is Polaris, and that's Capella as the brightest just above the lower horizon amid a few trailing clouds. The image shows a little less than half of the Milky Way's width (which is about 100,000 light years).
This location in Central Oregon has some of the darkest skies in the country. We camped amid obsidian flows (see the other image in this series) of all types and colors. It's a wonderful place.
