How to generate transition images between to images?

Hi.
I have a problem that I suspect IM could solve for me. I gues it woud require some scripting and I havn't a clue of where to begin. So I turn to you...
Only the first part I describe under, I don't know how to do, but I'll just include my whole intention with my images to give you the full picture of what I intend to do with them.
Problem:
I have several series of images of aurora borealis, and each series contains about 1600 hi-resolution images. This is from an exposure every 6 seconds thruout one whole night.
I plan to make a time laps movie of them, and I need to generate a fadeing transition between every image by generate several transition images between them.
There is not that much difference between six seconds on the nigt sky - even with aurora, and through small scale testing, I've found that a transition of 10 images is sufficient to get a nice "continious" feeleng on the video. But to generate this manually 1600 times just isn't an option. (and these numbers are just for one of my many image series)
I need a more smooth way of generating these nearly 15000 images. One suggestion is some clever imagemagick scripting. I love imagemagick - used it for years, but I'm not particulary good with scripting.
If anyone have some suggestions on this, I would be extremely grateful!!
The rest:
Later I will stitch these approx. 16000 images together to a hi-res. time laps vidio. This I know how to do.
The 16000 images correspond to one image every 0.6 second. If I use a framerate of 25, this would give smooth timelaps video of approx 10.5 min of the whole aurora night.
I could of cource buy photoshop and do this on a windows computer at work. A friend of mine says it's possible with som clever photoshop automation scripting. But my collegues continiously nags me (friendly of cource) for choosing linux on my private and work computers, so I refuse to do so out of mere principle
Hope some more skilled user could point me in the right direction. In advance thanks.
