1/2 gigapixel panorama of the
Milky Way center over La Palma

Details

This is my biggest success in astrophotography so far! Several months of different tests as well as different processing 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 much more in it.
It took me a long time to figure out how to stitch all the sky data into a perfect mosaic. Thanks to the help of @michael_ostaszewski I was able to stitch the sky perfectly in Astropixelprocessor, which took 3 days of computation!

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 128 frames in total.
104 for the sky and 24 for the foreground. It is my most detailed image yet with a total resolution of 570 megapixels!
