IC59 and IC63

IC59 and IC63 In Cassiopea

Date:

October, 17-18, 2003

Image Data:

IC59 and IC63 are 25 minutes apart and each 21 minutes from 2nd Magnitude Navi
(Ivan spelled backwards) or Gamma Cassiopea. Dithering the image incorrectly caused
some stray light to strike the ccd chip. The overall result to my eye was astetically pleasing,
so I left it in instead of removing it with a gradient tool.
