I’m currently registering and stacking nearly 800 multisession subs from 2 different (but close) image scales and have come across a weird registration anomaly.
Some of my subs have not registered correctly and look like the example shown.
It is not the case of only one image scale registering, as most from the same camera register fine with the other camera. The pre-processed garbled subs even look the same as the rest of the subs.
Hi, I haven’t seen this recently, if your input images look normal this is very strange… Does it happen always with the same images? Could you share the reference image and a failing image? Thank you
I tried your images, they are very different in terms of level, stars still seem to be detected correctly (more than 1400), but no registration solution is found. Are you sure they are of the same sky area?
What Cyril was talking about is an option in the registration algorithm, available in the GUI or as an option of scripts (-transf, see the command reference)
