I tried but it doesn' t look much better.
Is negative camera angle valid ?

Follow minor planet - or comet
I'm assuming asteroid or comet align assumes that north is up (and east west) in images.
How about when camera is not rotated like that ?
Would it be possible to read angle from fits and then calculate the angle of asteroid/comet based on that ?

Plate solving - single vs stacked
I just make image of recent supernova (SN 2020ue in NGC 4636).
Started doing astrometry/photometry but first plate solving.
But it was strange that I couldn't plate solve using calibrated and stacked image - uncalibrated single image solved fine.

Re: Trichromy - large images?
You were right that they were different size.
Good to know that there's going to be warning of this in the future.

Re: Trichromy - large images?
I tried both 64bit and LAA version and same result.
End mosaic size is about 5000 x 5700 pixels.

Trichromy - large images?
Is there a limit how big images can be fed?
I have made a 3x2 mosaic which is over 5000 pixels in size.
Now when I'm doing Trichromy and adding second channel it deletes the first.

If your script automatically detects new objects then I'm sure many would be interested - me included.

Re: Is 60s good enough?
There are so many variables in AP so no wonder there's 'conflicting info'. If you are going to image moderately bright targets then 60s might be enough - and you only need to stack less than 100 of them. But if you are going NB and image faint targets then you need hundreds (even thousands) of image...

Re: RGB horizontal stripes
Are you dithering ?
If not then you should.
There are ways to smooth those stripes but better to use dithering.

I can confirm it works your problem sounds strange.
Have you tried different area/image ?
