Weird repeating stacking artifact?
Any suggestions on what is going on in this image.? Same pattern but different colours. This is the only image I'm getting this weird repeating pattern all over the image. 30 flats, no calibration frames. Using pretty much all default settings on APP.
Hot pixels. Try making darks and a bad pixel map and apply those. Alternatively, you can play around with the outlier rejection settings.
Thanks, that did the trick. I didn't realise bad pixels resulted in such a repeated pattern across an image when stacking/integrating.
I used a Bad pixel map and also integrated with the 'quality' setting, and sigma kappa rejection set.
