NGC 6543, The Cat's Eye Nebula

With it's 300 arcsec outer diameter halo and even smaller inner core of approximately 16 arcsec, this planetary nebula in Draco is a challenging target with the Esprit 100 and a DSLR. After last year's imaging frustrations with this target, additional sessions yielded better data, though it was really the application of SPCC then separately developing in the linear phase before carefully stretching the starless and star images that made the difference. The pre-processing was a little more cumbersome because two different DSLRs were used with different sensor sizes, so WBPP could only be used thru the Debayer stage, then step by step through final integration. In the drizzle data, I was able to see a little bit of color and structure in the core, but the non-drizzled image looked much better so that it what is submitted.

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.
