Planetary nebula NGC246 in Cetus

(RA 0h 47.0m , Dec. -11°53', 10.9 mag., 225" in diameter)

This large, ghost-like planetary nebula really astounded me visually when seen through 8 inch SCT from southern Ontario in the fall of 1995. It is quite easy to find about 5°30' SWW of h Ceti (see finder chart below).

The above image was taken on November 10 and December 18, 1998 from Sooke, BC. Cookbook 245 LDC CCD camera was used on Celestron Ultima 8 f6.3 telescope autoguided with Cookbook 211 LDC camera on a piggybacked 500mm f8 telephoto lens. This image is composed of white integrations (14 x 4 min.) as well as cyan, magenta and yellow-filtered exposures (4 x 4 min. each) processed with Multi245, AIP245 and QColor. Color image was then re-processed in Lab color space using Corel PhotoPaint 8.
