Sun - 21.4.2022 at 10.49 Espoo Observation number 106358

Visibility Unclassified

Tommi Ropponen, Ursa (Etelä-Suomi)

I went on a coffee break to scrape the test material out of the yard. The aim of the description was to test what 12bit vs 8bit data looks like in the current case. As a result, here are a few final pictures. The wind was creepily strong for this grab & go system, but with transparency, the end result is pretty great. I wonder if this summer 2022 filming season is off to a good start.

More information about the equipment can be spy on astrobin: https://www.astrobin.com/19krty/

Addition: Two more animations completed. In these, the sun has been photographed during the same shooting for 18 minutes and indeed in a strong wind, which makes some of the screens smaller than others.
