Still more testing tonight. A stack of 53 x 60 sec lights. I didn’t shoot any flats at the time, but realising that I had not touched the camera for a few weeks, that when my new light panel came, that I shot some test flats and found that when applied to this, that it helped with a very minor background gradient.
