Final attempt at star trail
Hi All,
Finally have come up with a satisfactory alignment for a star trail image over my observatory.
Changed from 30 sec subs to 60 sec subs and I think that made the trails better. Weighing down the tripod base, making it more stable also helped as did utilizing the mirror lockup feature.
This image is 180 x 60 sec subs with 10 Darks. Canon 450D 17-85 mm lens at 17 mm F 4 and 400 ASA.
Built image in Star Trails.
Used IP 3.60 camera control and touched up image in CS4, slight brightness and curves tweak. Used the Noise Ninja plug-in for CS4. This really is my first experience with Noise Ninja and it does an amazing job.
My image looked very smooth from the beginning but when zoomed to 400% there was noise in it. A pass through Noise Ninja achieved pretty remarkable results.
I have included a crop of part of the original image zoomed to 400% and for comparison, the same field after using Noise Ninja. Hope they are large enough to demonstrate the effect.
Regards
Trevor
