About this image

Clear night but absolutely useless seeing in SE UK. However, able to integrate enough data to obtain a good image of NGC7331 and SN2026aaiv. (After cropping out a load of satellite trails)
Aperture photometry confirms what is hinted at through the eyepiece, that the SN has brightened slightly to be approx Mag12.9. The issue i'm having is the background brightness so near to the galaxy centre, but reasonably confident of this value having compared other known Gaia DR3 reference stars in the image.

Image minimally processed (darks and flats, averaged, plate solved, then photometry carried out) then very lightly applied Astroart DDP routine to suppress background and then annotated to make the image slightly more presentable as a record here.
