  The Cat's Eye Nebula (also known as NGC 6543 and Caldwell 6) is a planetary nebula in the northern constellation of Draco, discovered by William Herschel on February 15, 1786. It was the first planetary nebula whose spectrum was investigated by the English amateur astronomer William Huggins, demonstrating that planetary nebulae were gaseous and not stellar in nature. Structurally, the object has had high-resolution images by the Hubble Space Telescope revealing knots, jets, bubbles and complex arcs, being illuminated by the central hot planetary nebula nucleus (PNN). It is a well-studied object that has been observed from radio to X-ray wavelengths.

The RGB frames showing the nebulas core were blended into Ha data and run through Topaz GigaPixel AI to develope the details.
The nebula core from the RGB data was blended into the initial 4 1/2 hr. stretched Hydrogen-alpha (Ha) exposure and used as the base for the details. This layer was imported into GigaPixel AI to further develope the core details as shown below.
