This group of galaxies in Pegasus has triggered my interest (sure I’m not alone). I spent a lot of imaging time th elast few clear nights on these objects. It’s NGC 7331 and it’s “fleas”, and then Stephan’s Quintet, a small group of 5 galaxies close by.
I imaged this with three options 60x300s Esprit, 64x300s C11 and 122x300s Esprit:
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.
