NGC7000 SII filter Master Light Frame - 30 X 240s exposures

I used 60 DARKs, 60 flats by filter, 60 Dark Flats for calibration. Calibration, Star Alignment and stacking with PixInsight
ORION EON 115mm with ASI1600MM-C with ZWO 7nm Ha, OIII, SII, Lum filters - image capture with Sequence Generator Pro
ORION HDX-110 EQ-G with ORION 70mm/ASI290MM for guiding with PHD2.

The diffraction/interference pattern seen in the SII Master Flat did not calibrate out from the light frame. The same artifacts are visible in each light frame.
