IC 4592 - The Blue Horsehead Nebula

This image is the result of 4.5 hours of LRGB integration with my Askar FRA400 Astrograph using a ZWO ASI1600MM-Pro camera and an IOptron CEM26 mount.

This was shot over 4 evenings of 6-29-22, 6-30-22, 6-31-22, and 7-03-22.

This target was challenging for me for a few reasons. It is located pretty low in my southern sky, ranging between 22 - 25 degrees elevation. It also falls within the narrowest gap that I have between my two treelines! As a result, I could only capture about an hour each night before it was again hidden in the trees.

This is a large and faint object and really demands longer integration times - since that was not possible, for me given my location and circumstance, I had to do the best I could with the data that I had.

I really like this target - I love the shape and the colors and the fact that Nu Scorpii provides a nice blue eye for the horse just adds to the aesthetics!

I was surprised by how little data I was able to find about this target. I'd like to learn more about it so I will have to dig a bit deeper.

The story of the image and complete processing walk-through can be seen on my website at:

Thanks for looking, and let me know if you have any questions!

CS,
Pat

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.
