Cats Eye Nebula core cut out anotated
The Cats Eye Nebula in RGB Ha and O3. Imaged remotely from Spain with the 16in Dall-Kirkham and the Player One Poseidon M-pro...I am really liking this new camera so much cleaner than the previous ZWO with far superior cooling.
Exposure times were 60x 60s in each RGB filters, 240x 60s each in O3 and H-alpha.
Imaged at 1x1 then software binned to 2x2 Processed in Pixinsight and Photoshop.
Thanks for looking

Additional Info
Anyone who has imaged this one knows how difficult it is to pull out the core detail. Looking the stunning high res-HST image was very useful for reference making it easier to see similarities in the core structure.... I wanted to see if I was able to pull out those beautiful spokes, but honestly I think I was kidding myself to think I could do it with a modest 16in ground based scope. However If I squint my eyes to the point where they are virtually closed and believe like a kid at Christmas sometimes I think there is evidence of them being there!!!
The concentric rings or shells and the knotted jets however are a different story they are quite clearly shown, more visible in the O3 data, virtually nothing in the Ha and only a hint in the RGB. I did take some Helium data but it really didn't bring much to the party so I excluded it from the final image. You have to roll the dice once in a while!
