I am using a ZWO FF107APO and a ZWO ASI2600MC Pro, and APP for stacking.
All my pictures come out of stacking with a gradient across from deep purple on the upper left corner to aqua on the lower right corner, without any processing.
Any suggestion?20260114 Seagull Nebula ZWO wide filter light.jpg
I attached a recent picture of the Seagull Nebula.
Thank you for inputs.
