Star Trails at Elveden Again

 Another attempt at mastering star trails and this time pointing towards the north. The first composite has 20 images, the second 11 images at 60 sec intervals (30 sec, f4, iso 500 plus 30 sec processing). Obviously a slightly longer recording series is required to get a good spin. Interesting to confirm that the earth revolves around the north star and to see how the big dipper can be used to locate it!! The last two images show Jupiter rising in the east - a very bright planet. I lit the duck in the final image with a torch.
(NB. Need 75 mins of recording to get good trails, turn off long exposure noise reduction to reduce the processing time)
