The first more or less serious accumulation on the new tube 300/996 "Ed.No.3". The wind was very strong, the guiding was so-so, but still managed to accumulate a little during the still short night.

How did the stars stay in place if there was strong wind and they should have been somewhat streaked?

Only at the terminator, but there were peaks up to 2 seconds and some frames showed an error up to 1.3 seconds, while when it's quiet, around 0.6.
