Hi all

Does anyone have any pointers in regards to the warning: “No photometry stars found”
Never seen it before, and comparing frames I don’t see any apparent differences on the frames. 

Thank you.

I posted my question over here as well : https://www.backyardastro.org/topic/3977-normalizescalegradient-script/page/13/#findComment-35359 . I'm hoping that John can help.

I will update this thread as well.

Bit more details of the where's and how's would help immensely. As a hint: it does happen in areas poorly covered by photometric surveys, typically far galactic N pole.

It turned out that I had missed a couple of bad frames, which messed up the photometry in NSG.
