NGC 133

Combination of 6, 120 second images. Modified Canon Digital Rebel DSLR camera.
5" f/5 refractor at prime focus.

NGC 133, along with NGC 146, are a pair of open clusters in Casseopia, located close to the moderately bright star kappa cassopeae. (The bright star at the bottom of the image.) The two clusters are not overly impressive in binoculars, but appear better in the telescope. NGC 133 appears in the image above as a line of 4 blue stars to the upper right of kappa, while NGC 146 is a larger but fainter and more scattered cluster a short distance to the left of NGC 133.
