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.
