I am doing photometry and have calibrated my images and done a virtual stack. When I am trying to place apertures on my stack of 10 images, 7 of the images are aligned while 3 of them are not, but are aligned with each other. I tried just moving my apertures in the moved images, but that moved the aperture in all the images. Is there a way that I can either fix the stack or move apertures in single images rather than all?
