Okay, you guys have me hooked. I tried a few star trails last night and they came out okay but with not much aesthetic value. I think I need to try a recognized asterism as mpphoto12 did, or a wide angle with earthbound features included (as Colin did- I like that one).


What focal lengths and exposure times did you guys use? Colin's looks wider, and must have required a longer exposure (and a darker sky, I suspect). Did either of you try subtracting background glow?
