David,
By chance I captured an unfiltered image of Gyulbudaghian’s nebula at roughly the same time as you.
Mine is with an f/4 0.3m Newt, unfiltered and the product of 90x 30sec x2 exposures.
My unfiltered measurement of PV Cep sees it at 16.35, slightly down from a few weeks ago.
Have you considered redoing the analysis you did for your paper a few years back? The much longer duration dataset would make it interesting.
