NGC 3242 commonly called the CBS Eye or Ghost of Jupiter, is an exceptionally bright planetary nebula in Hydra. It is so bright, that I only needed 15 and 30 second exposures to get strong signals on all filters.
So the Final image is pure RGB, and the Original image is a combination of Ha and Oiii. The two versions bring out slightly different internal details. The NB version most closely resembles the CBS Eye, in fact, a marvelous likeness.

NGC 3242 (also known as the
Ghost of Jupiter or
Caldwell 59) is a
planetarynebula located in the
constellationHydra.
William Herschel discovered the
nebula on February 7, 1785, and cataloged it as H IV.27.
John Herschel observed it from the Cape of Good Hope, South Africa, in the 1830s, and numbered it as h 3248, and included it in the 1864 General Catalogue as GC 2102; this became NGC 3242 in
J. L. E. Dreyer's
New General Catalogue of 1888.This planetary nebula is most frequently called the
Ghost of Jupiter, or
Jupiter's Ghost due to its similar size to the planet, but it is also sometimes referred to as the
Eye Nebula. The nebula measures around two light years long from end to end, and contains a central white dwarf with an apparent magnitude of eleven. The inner layers of the nebula were formed some 1,500 years ago. The two ends of the nebula are marked by fliers, lobes of fast moving gas often tinted red in false-color pictures. NGC 3242 can easily be observed with amateur telescopes and appears bluish-green to most observers. Larger telescopes can distinguish the outer halo as well.
