My first attempt of a star trail which I did a week ago was a failure.
And I didn't get chance to try again (exams and clouds) till just then with beautiful clear skies. This time around, I think it is much better but I also caught two planes
and a meteor
(don't think it is a satellite as Calsky has nothing on it).
First Attempt
ISO800, F/5.7, 120x30sec
Second Attempt
ISO400, F/4, 231x30sec
Both taken with EOS-450D
