(RA 7h 29.0m , Dec. +13°15', 10.3mag., 615 arcsec. in diameter)

This large and faint planetary nebula recquires large aperture for visual observation. It is located about 5° N of b Canis Minoris (see finder chart below).

The color imformation for the above image was obtained on January 28, 2000 from Sooke, BC and luminosity data was acquired on February 4, 2002 from Harrowsmith, Ontario. In both cases, Cookbook 245 LDC CCD camera was used on a Celestron Ultima 8 f6.3 telescope autoguided with Cookbook 211 LDC camera on a piggybacked 500mm f8 telephoto lens. The image is composed of white exposures (10 x 600 sec.) as well as cyan, magenta and yellow -filtered integrations (1 x 600 sec. each) processed with AIP4WIN. The color was then adjusted in Lab color space using Corel PhotoPaint 8.
