Blue Horsehead Nebula with Comet C2017

Acquisition type: Electronically-Assisted Astronomy (EAA, e.g. based on a live video feed)

IC 4592, better known as the Blue Horsehead Nebula, is found 400 light-years away towards the center of our Milky Way, in the constellation of Scorpius. This large reflection measures about 3 x 1.5 degrees in size and is part of the Rho Ophiuchi Complex.
It gets its blue coloration from the bright star, Nu Scorpii, which forms the "eye” of the horsehead, and illuminates the dust and gas in the nebula.
The Horsehead Nebula is not as well known or photographed as many others. Being large and faint, it is difficult to observe visually and is shown best by deep exposure integrations.

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.
