I've been putting together a stacking program for some time and it's starting to give usable results.
Below is a recorded test run (stacking of 500 frames). Note that this is not the final performance – this run was single-threaded and the enabled “processing preview” slows things down (not to mention the screen grabber encoding in the background).

Linux – Fedora 23 (KDE). The code is of course portable (processing in a C99 library, GUI made with GTK/gtkmm) and will build and run on most platforms.

Take one processed image, and make it 75% transparent and place that on top of a final image that is 100% opaque.
Ah yes, the "processing preview" might change in the future, but in any case it's just eye candy.

I like what I'm seeing so far...will be very eager to try it out.
I'm sure you have your hands full but I would like to make a request...
Would you consider building in the ability to efficiently handle larger image resolution? Both Avistack and Registax max out at less than 3 MP. AS!2 was designed for similar image sizes however Emil told me how to make it run any size you want...while I'm grateful to have a hi-res option, the processing time for 1000 8MP images runs between 90 and 120 minutes compared to 3-6 minutes 1000 2.5MP images.
For the record I have blazing fast work-station class computers with loads of RAM and overpriced graphics cards...and 8MP data sets can take 2 hours...If it was down under 30 minutes I would be laughing...and I would try more animations.
FWIW I would be running 18MP data sets if it were possible...so let me know if you need higher res data sets as I can render at any resolution needed.
...anyway, that's my long-winded request...if you can do it...excellent! if its not feasible, oh well...I'm still looking forward to test driving it :-)

There is no image size limit other than available memory (and of course I'll provide both 32-bit and 64-bit builds for Windows), and memory usage during processing is rather light. As to how efficient the program will be for large images, we'll see - I'll gladly try your datasets once I've fixed some outstanding issues.

Do you use morphing only or more advanced reconstruction ?
I'm not sure Right now it's just "destretching" and linear interpolation within triangles. I'll prepare a technical description some time later.
