NGC 6543 - Cat's Eye Nebula

NGC 6543 Cat's Eye Nebula.

This beautiful planetary nebula is the remnant of a dying star, about 3000 light years away in the constellation of Draco (The Dragon). The interesting little barred spiral galaxy to the left is NGC 6552, which is a mere 365 million light years away! I'm always amazed at the vast distances we can see with our images.

My first complete image since February due to the weather and a first light test of my new Starizona SCT Corrector. The box did have a label saying "may contain clouds."

What a difference it's made, nice round stars and less vignetting. The star shapes are nearly perfect even in the corners! Back focus appears to be critical, so I used additional 0.5mm spacers to get close to 90.3mm for the C11.

Hoping to get at least one galaxy before the season finishes!

Clear skies!

Tony.

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.
