Data: mag 8.8  size 19.5"
Position: RA 17:59  DEC +66:38
Description:
I had to use 122X to be able to positively identify this planetary when
sweeping through the field for it. 188X provides a nice view in my
telescope. The oval shape is unmistakable, and is reminiscent of the Ring
Nebula in Lyra. The nebulosity appears to be a fairly consistent brightness
throughout, with little variation noted.
A fairly bright star in the same field acts as a visual companion to the
Cat's Eye, making focusing much easier. Dropping the magnification back down
to 49X reveals that the nebula is a brilliant aqua color.
