Pretty cool. The perspective is doing my head in a little, plus I tend to prefer trails no longer than about 20 or 30 minutes total myself, but you did a good job there. I prefer the second image.

cool image!

here is a question. why stack the images and not just do a very long exposure?

you would get too much exposure on the none stars and too much noise from the CCD chip in the camera as it heats up along with camera electrical noise.
