I just fed it my lunar mosaic images that I took on the 1st February 2005, it didn't quite do as good a job as I did manually but if I had more frames with a bit more overlap, it most certainly would've.. and there's no doubt it's about a thousand times quicker than me!
This is an 8 frame mosaic.. The version that I stitched together myself
can be seen here.
Great program!
