I'm processing the publicly available raw images from the James Webb Space Telescope. The raw mono images are taken using different wavelength filters and by assigning different colours to each filter a full colour image produced. The problem I have is that some filters produce images that are half the size of others, so in order to overlay them they have to be stretched then aligned using 'Align Layers by Stars' but I am struggling to get the registration perfect. Is there a better way to stretch and align these images?
