Vermont Night Sky II

Vermont Night Sky II

Another shot of the night sky in Vermont. This time with a shorter exposure to prevent blur and to reveal the galactic center of the Milky Way galaxy in detail. You could actually make this out with the naked eye! It was the first time I had seen that much detail in the sky. If you look at the previous star-trail image, what appeared to be a blurred cloud is actually the Milky Way.

When taking this shot, 30 seconds was about the maximum exposure time I could use without inducing star trails. However, at that short of an exposure, I need a pretty high ISO. To improve the noise response, I decided to take several high-ISO, 30-second exposures and then average the results afterward. However, to avoid star trails in the merged image, I feature-matched the stars so they would be aligned between images. This was my poor-man's version of an equatorial mount produced in post.

The final image is a combination of six 30-second exposures. You can see four of them by clicking on the "Show Unprocessed" button above. I managed to catch a shooting star in one of them.
