2015-12-10 Comet Catalina

This morning I grabbed the camera and mount and headed right up to the roof before breakfast. My socks were freezing on the hoarfrost, and it was quite cold in my T-Shirt, but then while the camera was happily snapping away at Comet Catalina I was comfortably eating breakfast.

This is a crop from the original image, 27 individual frames were combined using Andreas Roerig’s software Regim, additional processing was done in Adobe Photoshop and Lightroom.

On December 11th I updated the images, as I found out the de-bayering in Regim was configured wrong, also I applied different settings for gradient removal, resulting in a background with less artefacts, I also included 10 more frames for a total of 27 sub-exposures.

In the inverted version the visible tail is 4,4° long.

On the morning of December 7th Venus and Comet Catalina got close to each other in eastern sky.

Comet C/2014 Q2 Lovejoy

Another bright Comet Lovejoy with the designation C/2014 Q2 Lovejoy is grazing our skies these days.

The comet’s path takes it north next to the constellation of Orion, making it conveniently placed for nothern hemisphere observers.


Yesterday’s sky was a bit hazy as the temperature dropped quickly and humidity condensed in the air, additionally light pollution creates a bad gradient in the west of my home.

Trying to catch ISON, got Lovejoy instead


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.
