I am using Photoshop CC2019 latest updated
I try to use Auto-align Layer in Photoshop but it seems doesn't work.
previously I can use it with no issue many months ago
** my photo is moon photo I want to stack them to get more details so that I need to do auto-align before stack.   All of my photo are almost in the frame that should be overlapped

Did you use the scripts "Load images into stack" or "Statistics" respectively? Both also have an align-option in their dialogs. Maybe that works.

The problem is in the dialog. The images, when taken, don't overlap enough. Couldn't find the files you supplied to support in the case notes, but I did see a note from them that the images didn't overlap by 40% or more - sending you here to request for us to try and make it work. I don't think it's possible because the algorithm needs input data (overlapping areas) to work. You can post sample files here. The workaround is to manually align them and then use the "Auto-Merge" function to blend them together.

I'm facing the same problem, also trying to stack images of the moon.  Photoshop is broken.  My images overlap close to 100% so this is a bug in Photoshop.  So frustrating.

If you open the two image in photoshop and select blend mode difference, we can see the images overlap nearly 100%, but photoshop claims it's less than 40%.


I spent an hour explaining this to chat support and they agree it was a problem with photoshop.  I don't want to have to write my own software to align layers, so can we get photoshop fixed?

The problem in this case is probably that Photoshop does not see any details in the black areas that it can use to align the images. That means that 60% of the images does not have anything it can use. Remember that Photoshop sees an image as a bunch of pixels, not as a moon in a black sky.

Another problem is that the stars that are visible in both images are in a different place, and these would be the few points that Photoshop will try to use in the black areas. It's easy to manually align the moons (using Difference blend mode), but then the stars are clearly misaligned.

Minimizing the RMS of the differences between the layers would align the layers better and faster than I can. The stars would contribute very little to the total error. When will this be fixed?

you need to crop the image as close to the moon as possible, then it will work ok
