Cat's Eye Nebula

Cat's eye nebula, a.k.a NGC 6543, and Cadwell 6. A planetary nebula in Draco ~ 3000 ly away with a magnitude of 8.1 and high surface brightness. It was the first planetary nebula whose spectrum demonstrated that planetary nebulae are gaseous in nature and not stellar. Structurally a very complex nebula, the mechanisms that have given rise to its morphology are not well understood yet.

HSO 13h 20m (24:28:28 x 600s) false-color image from SPA-2 an Officina Stellare 700 RC telescope, with FLI PL16803 camera and Astrodon LRGB 2GEN filters on an Officina Stellare equatorial fork mount with absolute encoders and direct drives. Situated in Oria, Spain. Part of telescope.live telescope network. Taken on multiple dates March 2021 - June 2022.

Processed in PixInsight. Color mapping was done using Alex Woronow's Narrowband Assistant script. Most of the bright core was unresolvable with 600s exposures; probably, short exposures would have helped.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
