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:
The same area, this time imaged the next night October 5th, with the C11, Starizona F7,2 reducer, Nikon D750 64x300s on ISO 800 SQM= 20.15
