A Ring around the Moon
An incoming layer of high cirrus clouds announces a change in the high-pressure weather pattern. The ice crystals in the clouds create a highly visible 22° ring of light, also known as a halo around the first-quarter moon.

Recently I spent a night in the Alps at 2000m height. I slept outside in a bivouac bag and enjoyed a very dark sky.
I took the picture above with the camera on a small tripod, and made 5 exposures which I later combined into a single picture using IRIS.

Yet another M42 image…
After a very long summer-break in Astrophotography, I found myself with time on hand on a clear evening. After I did a series of 4 300s images for the Plejades (see below) I set the scope up to capture a few light frames on M42, the Great Orion nebula. But while I was sitting in the living room trying to get warm again, watching the Soccer Champions League, the D200’s battery ran empty, and I ended up with only one long exposure. I used the single 300s exposure with a much shorter exposure to get some detail in the very bright center of the nebula to get this picture.
