Unexpectedly the astro weather prediction for the weekend was very good, so I started with NGC 1579 a new LRGB project. Unfortunately, during the night, there were sudden problems. The guiding stars got lost although there was no cloud in the sky. The known Maxim DL problem? I had it never before with the Newton.
After the session at the following morning, I could count 45 luminances of 600 sec in my poket. Here is the image - already slightly processed.
