NGC 6543 CAT'S EYE Nebula 15 HOURS OF INTEGRATION. A truly faint deep-sky object that required stacking 15 hours of integration over 5 nights.Some info: NGC 6543, also known as the Cat’s Eye Nebula, is a planetary nebula located in the constellation Draco, about 3,000–4,000 light-years from Earth.It formed when a Sun-like star reached the end of its life and expelled its outer layers of gas, creating a glowing cloud.It is one of the most complex nebulae ever observed, featuring intricate structures such as concentric rings, high-speed gas jets, and dense knots of material.Its estimated age is about 1,000 years, and its structure acts as a kind of “fossil record” of the final stages of the central star’s
