Day #1795 Title: Heavenly Bodies
Location: Ingatestone
Camera: Canon EOS 7D / 100mm EF f/2.8 L IS USM
Notes: I have been meaning to try my hand at some star trails for most of the year, as it is Treasure Hunt theme #45. Tonight was finally the night! Very cold, I first had to scrape ice off the car before I went anywhere this evening! Then I headed to a spot which I hoped would be reasonably free of light pollution. Wrong! It didn’t help that there was a full moon, which pretty much overwhelmed any images made looking east, especially with the 10-22mm wide angle. So I tried my hand looking west, with the 100mm prime, in the hope of accentuating the stars’ movement in the  sky. Thanks to this excellent article on how to choose your exposure, I got some good initial pictures quite quickly. Then it was just a case of waiting. This is a composite (stacked with the free Startrails.de software) of 50 x 30s exposures @ f/2.8 and ISO 160. I took more, but the later images were obscured by thin high cloud, so I discarded them. Originally I was rather annoyed that I’d randomly chosen a region of the sky where aircraft regularly pass, but when I built the stack, I actually quite like the result (the straight lines on the left)! I was also amazed at how vivid the different colours are for each star trail. I nearly froze to death, but I’ll be having another go soon (probably when the moon is new).
