I have discussed some of the maths involved in aligning images when the camera was not pointing in a fixed direction – hereThe algorithm is built into my own image processor, GRIP, which you can download from my site (from the link above). This is non-commercial software I wrote (and continue to develop) for making my own astrophotos. I’d be interested to know whether it helps in making analemmas.(I think your main problem though is going to be getting regular cloud-free days.)
