Cat's Eye Planetary Nebula - NGC6543 - Caldwell 6

This picture was not easy to make : my stars are very elongated on lots of series of subs - probably poor polar alignement (my mount is on a Berlebach tripod... on a wooden terrace that moves when I walk on it... but no choice to do otherwise... except changing of house !) - and my filter wheel is not very precise, leading to flats that maybe offseted if I change filter before making them....

Anyway, I tried to overcome all of that using PixInsight and Photoshop. I had a lot of pleasure learning to use some of the PixInsight tools to deal with such a high dynamic range between the core and the gaseous enveloppe.

Now I want to try to get the core using Lucky Imaging and an agressive Barlow (x4 !). Just for the fun, knowing that with a 8 inch aperture, I won't get much contrast into small details.

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.
