Weird thing happens during registation in PI

[JCIdaho]

Hi,

(edited, - please see my next comment in this thread for a more accurate description of my issue)

Please, any idea why this registration would result in the attached?

During calibration it checks out OK - also attached.

This is for all my R images - the L/G/B came out just fine, with the same bias frames etc.

Thanks!

Are you saying the registered image is the one at the top and all the lights as per the bottom one? If none of that is correct I'm assuming you have lights with differing views that have resulted in the master looking different to the other filters. Unless I'm completely missing what you're asking, sorry.

Apologies for this @scotty38. Please see the below two images I originally meant to post.

One is a sub after calibration:

The other is the same sub, after calibration + registration.

I've never seen this kind of weird lattice pattern before.

As mentioned, this sub is the R. All the post registration subs have this problem. The other L/G/B subs are absolutely fine. The R flats look OK, so I'm just puzzled.

thanks.

I'm pretty sure I've seen this before but cannot recall what the issue was. Can you share the wbpp settings and maybe some files to try?

What does the Red stacked image look like when stretched?

The pattern looks like the pixels of the sensor but as this is one sub, which is part-way through the stacking process, then it would be interesting to see the final stacked image to see if pattern remains.
