As my main target that night (Monkey Head Nebula) went below horizon at 0:45 from the current position I was searching for other targets that would be visible from that time until approx 5:00.
Having the NBZ filter for that target is far from optimal, but the filter was needed for the monkey head and I did not want to stand up to change filters but also not "loose" image time.
I used SPCC trying to calibrate as good as possible - I think the result is quite OK.
