Mosaic of California Nebula in Perseus
California Nebula is a large emission region associated with a "run-away" star x Persei (see finder chart below). For another example of such phenomenon see Flaming Star Nebula in Auriga.
The above mosaic was assembled from 21 images taken on September 18, 1999 from Sooke, B.C. I used Celestron Ultima 8 SCT at f3.0 and Cookbook 245 LDC CCD camera. For each tile, five 60 sec. exposures were taken through infrared blocking filter and then combined with AIP4WIN.
The above image is reduced to 27.5% of the original. North is up.
Map created in Guide 7.0 - 7°45' x 12°. North is up.
