NGC 6543 - Cat's Eye Nebula (HA/OIII/RGB)

The Cat's Eye Nebula (also known as NGC 6543) is a planetary nebula in the northern constellation of Draco. It lies about three thousand light-years from Earth (Source: Wikipedia)

I am revisiting this target using my Esprit 120ED, so this is a heavily cropped version of last year's attempt using the EdgeHD 8. This started as an experiment to compare if the EdgeHD imaging scale (~0.5 arcsec/pixel) would give me any advantages from my balcony over the Esprit 120 (~0.9 arcsec/pixel). And it ended up being a full project. The jury is still out on the resolution part, but I think the Esprit FL is better for my skies.

This is mainly an HOO image, with two sets of exposures for each of the filters, then combined as an HDR composition, in order to tame the super bright core. I've also collected RGB data for the stars, the galaxy and the nebula core colors.

Clear Skies!

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.
