You've done a very nice job with this drawing, which shows why NGC-6543 is known as the Cat's Eye Nebula. It also seems you've spotted hints of the whorls that show so clearly in photographs of this very bright planetary nebula.

Nice sketch. I never saw it that "blue" in the EP.

voyger75,

I also see it blue but just a bit more grey than you see it.
Nice sketch of this beautiful planetary.

Frank :)

Hi everyone
Maybe I have a bit exceeded with color, however the same Hershell observing this nebula reminded Uranus.
Many thanks to all

No, I think you are close, although I see it as a bit more bluish-green than pure blue. However, people's eyes have different responses to the OIII emission from the nebula, so the exact description of the color will vary from individual to individual. What I see in NGC 6543 is a bit more of a rounded oval than one with pointed ends, along with a very diffuse outer boundary or shell. The central star is a little curious in that it "appears" at 50x to 75x fairly well, yet at much higher power, it becomes harder to see. I suspect that some of what we see as a "star" in the middle of the nebula at lower power is just an inner brighter patch of nebulosity that sits right around the central star combined with the light of the star itself. Keep up your drawings and clear skies to you.

There's a nice *BLEEP* cat!

What I particularly like in your sketch is you've managed to keep the PN nice and small, and still introduce detail. Tricky thing to do, :applause: !

An excellent observation of the Cat's Eye Nebula (NGC 6543). You have captured a nice amount of detail over it. Thank you for sharing it with us all.

Hey! Why the *BLEEP*? 'P,u,s,s,y cat' is offensive?

Cripes the automated censor is a bit trigger happy, isn't it! It needs a touch of context written into its programming.

Nice sketch! I think you captured the true nature of this object nicely, along with the blue color.

Clear Skies,

What a great sketch of this show-piece planetary. It's been awhile since I took a look at NGC 6543, but do recall seeing it fairly aqua in even pretty small scopes. I seem to recall reading somewhere about color perception having some variation between people when it comes to smaller, dimmer targets.
