Pawel, Daniel's suspicions proved to be well founded. Your images can be stitched very well, which would suggest your head setup was satisfactory.
There's a 6000x3000 jpeg at http://ge.tt/4lsO3Uk1/v/0?c Some minor parallax problems can be seen, though, on examining the images in detail. NB. I used only half of the number of images supplied in the above stitch. The rest were surplus to requirements as there was ample overlap. I also stitched with PTGui rather than Hugin, but Hugin should produce a similar stitch using the same care that I exercised. I did do another stitch using the entire set of images and that was fine too. I would also recommend taking a zenith shot to help clean up any potential problems resulting from blending 12 images overlapping at the zenith.
