Comet 64P/Swift-Gehrels

I was actually heading to bed when I noticed, that the sky cleared up enough to try to photograph Comet 64P/Swift-Gehrels.

As I wanted to create an image that included the Andromeda Galaxy, I used the 70-200 zoom and set it at about 130mm.

Comet 21P/Giacobini-Zinner

Comet 21P/Giacobini-Zinner is a short period comet of the Jupiter family.

This year’s apparition is quite favourable, as it places the comet in the evning sky. Best visibility should be around September 11th, where it should almost become naked eye visible. In binoculars or a telescope it is already a nice view. I observed it with the 127mm refractor, where it visually showed a short tail. Read More

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.

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.

18.1.2015

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.
