IC4592 - Blue Horsehead Nebula

Revision title: Reprocessed, artifact removal

This is the Blue Horsehead nebula shot on a single night from a Bortle 1 site at Mount Mulligan Australia.

Unfortunately, a combination of technical gremlins and a late night ground fog that rolled down the mountain prematurely at 3:00am served to cut short my planned imaging session. This was captured on the last night of my trip and as a result I had to rush through RGB. In the end I was only able to capture 2 RGB frames per filter, which lead to a difficult processing session with lots of cosmic rays and noise to work around.

All things considered though not a bad result. As with all the targets on this trip, I chose variety over integration time and the time compression on this final image cost me. I look forward to adding more data to this project in the future.

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.
