135mm 1/2 gigapixel panorama of the
Milky Way center over La Palma version 2 (2022)

Details

This is my biggest success in astrophotography so far! Several months of various tests as well as different edits and settings have brought me to this result 🙂

My 135mm half-gigapixel panorama of La Palma version 2. The first version was far from good by today's standards and I knew there was a lot more in it.
It took me a long time to figure out how to stitch all the data of the sky into a perfect mosaic. Thanks to the help of @michael_ostaszewski I was able to stitch the sky together perfectly in Astropixelprocessor, which took 3 days of calculation time!

The processing of the sky was done in Pixinsight with many different adjustments in Photoshop, where I also blended the foreground.

The image consists of a total of 128 individual images.
104 for the sky and 24 for the foreground. It is my most detailed image to date with a total resolution of 570 megapixels!
