North American Nebula - NGC7000
These four views of the North American and Pelican Nebula were taken near the zenith with progressively higher focal ratio camera lenses. The first image (top left) was taken with a 15mm Fisheye lens which features a broad expanse of the Milky Way. The North American Nebula can just barely be made out on the left center of the image. If you look closely you can also see a small round emission nebula IC1396 on the left side of the image which contains Hershel's Garnet star, a bloated red giant and one of the brightest carbon stars in the sky.
The image on the right was taken at a focal length of 35mm, the middle image at 135mm, and the bottom image at 200mm. Image details are provided below.
