Summary
[edit]DescriptionM101 Mosaic (noao-02881).jpg |
English: The well-known spiral galaxy M101 was imaged by Dr George Jacoby at the Kitt Peak National Observatory's 0.9-meter telescope, using the new wide-field imaging system Mosaic. This instrument combines the pictures from eight separate CCD chips, carefully mounted next to each other for a total of 8192 pixels square, and can thus image a large area without sacrificing resolution. M101 (NGC5457) is a type Sc spiral galaxy in the constellation Ursa Major and is quite similar to our own Galaxy. |

JPEG file comment | m101 made by assembling 3 b/w images from mosaic. this is like 2880+flattened and spikes removed. dr. george jacoby made 3fits images on a log scale available to bruce bohannan, bruce truncated the images at 256 shades of gray and passed them onto mark hanna in the photo/imaging dept. whomaximized the images for color and contrast etc. |
