In one freezing night, Martin, LEO, Ming and I headed to Blue Mountain Echo Point for having star trail shoot out. Thanks for Ming's good luck and we were able to see cloudless dark sky and saw some magnificent star shows including star clouds and tens of shooting stars.

I took 3 shoots with my F80 in that night and set my lens at F2.8. And this shoot was exposed for 30min (2:30am to 3am) at ISO 100 film.
