It's pretty easy to shoot these manually too - you don't need to have Litchi. But it is amazing to press Go and it shoots all 26 photos like I used to do manually! If you're in doubt, just get a trial version of PtGui or whatever software you like for stitching, take 26 shots (3 rows of 8: level, down a bit, down more, then one each way pointing straight down) and load them up. You'll see how easy it is.
