Holmes comet 19 days after the outburst

The night November 10/11 was really crazy. The freezing rain and snowfall alternated periods of excellent clear sky with perfect observing conditions. Several times, I had to cover the equipment with my jacket and wait for the weather turning fair. Finally about midnight of the local time a longer period of clear sky enabled me to take an unbroken sequence of 51 images. I used my most favoured optics - Rubinar 5.6/500mm.
Before the perfect weather came, I took several images on which I did not realize that even though the sky looked clear, the strong wind was bringing some snow flakes which were scattering the light of bright stars. I excluded these images from processing. Later, I browsed these images again and I found out that they have a fanciful beauty. Therefore, I made another version of the image presented on this page which is not made from perfect images only but also from images with scattered light caused by snow flakes.
