This time I have tried to click STAR TRAILS. I have used my SLR camera (film) for the above photograph as my digital camera is not capable to take the above photograph. To get this result I had to keep the shutter open for around 90 minutes. The main requirements for this photograph are complete clear sky and absence of moon and artificial lights.
The best night for this photograph would be new moon day with lots of stars.
The absence of artificial lights and moon would be beneficial for minimizing the chances of over-exposing the photograph and erasing the star trails (personal experienceJ).
