294 MM Pro banding in Narroband

Agepi7o

In my last two sessions with my 294MM I've got severe vertical banding issues after stacking with Pixinsight. I've redone all my flats and darks and the problem is still there with my Ha an Oiii filters. I use the camera at BIN2, Gain 120, 5 minutes subs with a Celestron Edge 8 (1430mm and F7). I've read somewhere that it may be some kind of defect in my camera. I attach the stacked Ha and Oiii, the 300segs masterdark an a sub of Ha .

Thanks

Agepi7o From the picture, these vertical lines does not appear in master dark and master light without calibration fields, only in the calibrated master light?
In this case, it may casued by some calibration algorithm, such as dark optimization, uncheck it to try.

Tech@ZWO Thanks, it may be so because if I use another software to stack (Siril instead of Pixinsight) they don't apear.

Thanks again

In case anyone is interested I solved the problem unchecking the linear defects correction in Insight , just that and the banding dind't appear.

Thanks
