Gidday All,
I thought to share this use of ImageJ to pre-process your images or align them and produce an set of centered images. The example I have will make an image set with a comet correctly centered in the the FOV.
You can change the output image size to make a crop from large mega pixel images.
You may find this useful to pre-process your planetary images to make the planet centered before you use your favorite commercial program to make a master image.
A PDF can be found on my Google drive here,

Let me know if you like it, and have any questions about ImageJ setup issues.
kind regards, Alan Watson
