Comet Neowise: Stacked Image

Stacking a set of comet frames can become a real pain, since the outer solar visitor travels much faster than the stars (not exactly right, because the stars don`t move, but it looks like that because of the rotation of the Earth). So if you stack a set of frames, you either limit your set to a maximum of about 10 min. of total exposure time (before the comet starts blurring), or you use all of your frames and stack one for the stars and one for the comet, and combine them. This option didn`t work out for me this time, so I stacked 10 frames (out of 35), 60 sec. each. One can`t believe, how much more information a stacked image got. I`m using Pixinsight, a processing platform specialized in astrophotography. It got a steep learning curve, to say the least; because of that, I`m more than happy with the outcome. Enjoy!

The Beauty Of The Night Sky

In my adolscent days, I spent the nights out partying with my friends, these days I silently spend them photographing the night sky. Have not been out at nights for almost one year now, so it got time to travel to my favorite destination in the foothills of the Bavarian Alps. Lots of people around at this time of the year, even more after loosening the coronavirus restrictions. But when the night falls in, everything calms down. Silence and solitude kicks in – what I like most. Enjoy!
