The seeing seemed quite stable here tonight so I thought I’d have a go tonight at doing a set of very short exposures of V482 Cyg and selecting the best ones to stack. This gives very high resolution and allows a clear separation between the variable and the 15th mag star to the NW. The variable has certainly brightened relative to that star since the image I posted on Aug 13. This image is only 3 arcmin square with a pixel resolution of 0.14 arcsec. Given that I’m not on a mountain this is probably as good as I can get.

The FWHM is around 1.5 arcsec and the circles are apertures of 1.7 arcsec radius centred on the Gaia catalogue position. This is unfiltered so the variable is likely to be quite a bit brighter than V would give.
