This is a wide field image of NGC 6543 (a planetary nebula) showing a wider region with background galaxies and Quasars. It has several common names - "Cat's Eye Nebula", "Sunflower Nebula", and"Snail Nebula" NGC 6543 is about 4,455 light years distant. Within its structure is a bright knot with a designation of IC 4677; the central star has a designation of HD164963. The main challenge with this target is the extremely large dynamic range. I chose to present it with structure from its extremities to its bright core.

In the wider field are galaxies NGC 6552 and PGC 61111. These are at distances of about 357 and 360 million light years respectively. There are several other PGC galaxies in background and some fainter, smaller galaxies that can only be seen in the full size images. One of these galaxies, PGC 94832 is notable in that it lies at about 1.126 billion light years distant. Three Quasars are identified in the annotate image. One, RX j17594+6638, has a very large redshift of 4.238 and a light travel time of 12.3 billion years - it is visible in the full size annotated image at full magnification.

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.
