Description: Cat's Eye Nebula. Very high surface brightness and stands well high magnification. At this time 600x were in use and it showed a tricky ring structure. The ring is elliptical and blurry in both ''heads''. Central star is petty bright but somewhat difficult because of nebula's brightness. Clearly turquoise blue.
