I struggled with aligning both, solar and lunar eclipse images with available SW like Autostakkert or PIPP and ended up writing a very simple tool to allow aligning images semi-automatically. The tool allows to
  • register using FFT and SSD
  • selecting a specific anchor area of the image to register against
  • manually shifting/rotating images
  • display absolute difference for fine alignment
  • linear morphing between images, to create a smoother animation


Known issues:
- all images in the selected folder are loaded into memory, if you have a lot of images, have a lot of memory
- i need to move processing into QThreads, so right now you cannot cancel anything

There is lots of better software out there, but a fun activity to use Gemini to write this code and maybe someone finds this useful as well

Very interesting tool and it looks very useful. I really like the way you configured the UI layout. I'll give it a try with my lunar eclipse images!

Great, let me know if you find any bugs. I did a lot of changes over the weekend. In the repository you can find some example lunar eclipse images for testing if you don't have yours at hand.

I did some fixes and updates to the tool. Mainly adding a manual 2point rotation method to get the rotation for tricky cases like my hand-tracked Venus transit data from 2012. result.jpg
Managed to somehow salvage this into https://app.astrobin.com/u/mxpwr?i=1vfr2l#gallery
Curious to hear how others solve this?
