Will using a fast telephoto lens give good results for star trails...I know most people use a wide angle but I was thinking of giving it a go with my 70-200 2.8...What are the down sides of using a longer lens? I Would have thought a longer lens would show the stars movement more for the same exposure time as a wide angle..
Any comments would be appreciated.....

I think people, myself included, use wide angle lenses for star trails is provide context i.e. the landscape. You'll certainly see more movement for the same exposure time and it could provide interesting results in terms of the detail and colour variation between stars. The result might look a little abstract though, but that can still work. I'd say just give it a go and see what you think! Don't forget to share what you end up with.

Yes - on purpose I captured those fireflies.
We have 2.5 acres and do NOT apply any pesticides.

Maybe this crop shows them better?
too much dark space at the bottom did not add to the image....

I took a night photography class at Crater Lake a year and a half ago. Hard to believe it took me this long to process my star trails! The moon really lit up the landscape. I will probably go back and clone out the headlights on the left side. All in all, very happy.

Those are most likely clouds, I've had them make my star trails look similar before, they even seem to apart motion in the image at times, like this one

yes they are clouds.
I could have left them out by skipping the frames that has them, but I liked the effect.
