Last week’s snow has almost completely melted and the stars are reflected in the resulting puddles of meltwater.
This image is a stack of 38 individual exposures: Nikon D7000, Walimex (Ssamyang) 14mm f/2.8, 30s at f/3.2, ISO 1600. Stacked in Startrails, edited in Photoshop (airplane removal) and Lightroom.
Yet another month has passed and the Moon joins Venus in the morning sky.

The California Nebula (NGC_1499) is a HII emission region in the constellation Perseus, it was discoverd by E.E. Barnard in 1884 on long exposure plates.
Because of the red color and it’s faintness it is usually only visible in photographs.
I used my unmodified Nikon D7000 camera in combination with the Nikon AF-Nikkor 85mm f/1.8 for this photograph. 11 individual exposures of 120 seconds at f/2.8 were combined using Regim by Andreas Rörig. Additional adjustments were made in Adobe Lightroom.
Last night I did some last tests in preparation for upcoming travel.
Today the sky cleared up pretty well, and I was able to get some more exposures with the Polarie:

In preparation for an upcoming trip I am doing some equipment tests to prepare for the opportunity to observe from a dark sky.
It turns out even with the very rough polar alignment that is possible with the built-in peephole of the Polaire tracking mount 30 second exposures are possible with 180mm focal length on an APS-C camera:

On January 30th Venus and the Moon joined up in the morning sky for a lovely conjunction:

On November 17th I decided at 1:00 to try to take some pictures of comet ISON before it’s rendezvous with the sun.
To get above the fog in the Rhine valley I drove up a still-open (normally closed in winter) mountain pass.
I arrived early at the Furkajoch (a mountain pass in Vorarlberg), so I had the chance to take some pictures of the alpine landscape and of comet Lovejoy.
The full moon and a thin layer of high cirrus cloud made the process of locating and imaging the comet difficult.
While bivouacing with my family high in the Alps I took some wide-angle shots of the summer sky:
Nikon AF Nikkor 20mm f/2.8
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.
