Hi all. I want to batch process my planetary work.
As describe in doc, only :
shift, similarity, affine ou homography
are available and seems psf based, so can’t be used on planets.
Is there a way to add an option to register planetary pictures ?
No.
All planetary registration methods are not scriptable.
Ok. Will it be available a day ? 
not in a near future.
The explanation is quite simple. Yet we need to make a selection around the planet to make it work. It is not really possible by script.
Someday maybe we will improve these algorithm to implement multipoint registration. But this is a long term schedule.
