Sleeping during a workweek is important! so this image was made unattended – counting on good luck. At the start of the session around midnight the sky was still covered with some high cirrus. At least the street lighting was already switched off.
Image data: Nikon 180mm tele F5.6, no filters, 82x180seconds or about 4 hours of data. It proves the IFN is also visible from light-polluted area’s without the use of filters.
