a few years back made this lame attempt at capturing star trails...it was dark at the time, but clearly 68 seconds was not nearly long enough for the exposure, returning the sky to blue but not catching much by way of trails...on an imminent trip hoping for another crack at this...perhaps should try for at least 5 minutes at first, and adapt from there...maybe best to pack along a sandwich and a thermos of hot chocolate, just in case the exposure times get ridiculous
