IC 4593

This object is a tiny planetary nebula located 10,500 light years away in the constellation of Hercules at a declination of +12 degrees. This PN spans just 12 arc-seconds in our apparent view, which is a bit bigger than the apparent average size of the planet Mercury to us. This is the smallest DSO object that I have attempted to image. Sigga needs her reading glasses for this one, for sure!

The actual diameter of this PN is 0.7 light years. The central star is clearly visible. The color of this PN is commonly described as emerald, which looks right to me. This is the 71st object in Stephen James O'Meara's Secret Deep DSO Catalog.

This object has the nickname of the White Eyed Pea. I guess it fits fine, but I think this delicate deep space object deserves better than to be compared to one of my least favorite vegetables.

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.
