A rare clear evening (amidst the rain and gloom) saw me head down to the beach to try another star-trail shot.
My previous efforts HERE had shown me that a single exposure of longer than twenty minutes, even with long-exposure noise reduction activated, tended to result in excess digital noise, as well as picking up too much noise pollution from the city lights. This evening, I decided to try a different approach, and took five ten-minute exposures, one directly after the other, and combined them, along with a single dark-frame, in this free startrails application.
Here's the result:
I would have liked to have combined more shots for longer star-trails, but the clouds soon rolled over, so I headed for home.
