A Horse, of course, of course:

Here is the beautiful region near Nu Scorpii.

I am still collecting images of the nebulae in this unique part of the sky and this is one I have never taken a widefield image of. I attempted to acquire data on this last year and spent more time on it this year. I didn't publish last year's attempt because there were too many issues with the data. However, this year a new processing tool became available that permitted me to salvage the data and add more.

The bluish reflection nebula around the "eye" of this horse head is IC 4592. IC4601 is the other reflection nebula. You can see an image I took of it more than a decade ago here:

I hope you enjoy the view. (I am pretty certain Alan Young would. 🙂 )

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.
