Very impressive for a white zone! I can't even imagine how you can get such a result with all those LED streetlights, even with narrowband filters!

Thank you! Low SNR can be overcome by increasing the total integration time, multiplied by the efficiency of the f/2 system. Fortunately, nothing interferes with this on the balcony—not a single night with suitable weather is missed. But a magnitude of 10 is probably the lower brightness limit for my setup.

F2!? What coma corrector do you have that gives such a flat field!? Or is it an aplanatic system?

This is a RASA - a Schmidt camera with a field corrected for a flat sensor.
