NGC 1360 - The Robins Egg Nebula

[TR (Terry)]

I shot this target a few years back and was not that happy with the result, I was plagued with guiding issues which really made processing challenging. This attempt has more broadband light in an effort to get more stars within the nebula.

This large, beautiful planetary nebula can be found in the constellation Fornax. Its common name, “The Robin’s Egg Nebula” describes the object perfectly. It looks like a Robins egg floating in space. NGC 1360 is a typical evolved planetary nebula. The term evolved means “aging”, and the planetary nebula does not contain any apparent shell morphology. Contrasting this, if you compare this with another planetary nebula, i.e., “The Skull Nebula” you will find defined, well-marked boundaries and symmetry present in younger Planetary Nebula (PN). NGC 1360 is fairly diffuse and shows areas interacting with the interstellar medium.

The interesting colouring is caused by the excitation of oxygen from its hot central star. The central star is known to be a binary star system consisting of two evolved white dwarf stars.

Reddish jet-like glows along the longer axis are believed to have been ejected from the original star before its final collapse. In time, everything will fade, with just the white dwarf in the centre remaining. It will take several billion years to finally cool off.

That is excellent picture and great detail, I guees the hours on it paid out. Will need to give this ago soon and see what I get.

Lovely result on this one Terry, it's a delicate but cool looking object and you have brought out those Ha jets very nicely

Planetary neb are very cool. Thanks for the feedback.

Thanks Mike. I love how you can see galaxies through the nebula.

Very impressive, and look at that ring galaxy on far left

Beautiful image, Terry. Your patience in accumulating this huge data set seems to have paid off!

Unusual and very interesting object. Must have been tricky to process - nice!

Yea, that is very cool. I had to keep that guy in the frame.

Thanks Rob. I enjoy processing planetaries and small galaxies.

Excellent result Terry, definitely adds so much more when the effort is there to get deep LRGB in addition to the NB (adds so much more than just star colour).
