M16: The Eagle Nebula in SHO(L). A test after a power surge damaged my observatory.

A short exposure of M16 taken using my *new* observatory computer. In late June, a carelessly buried section of the observatory power cable cable had an unfortunate encounter with a lawn mower blade. Fortunately this was a CGFI cable, but the surge lasted long enough to severely damage the computer. It seemed OK at first but slowly got worse. After 2 trips to a local computer shop I declared the computer dead and replaced it. Throw-in several trips and vacations and most of June and July yielded no images.

This is a very short exposure SHO(L) image of M16. It started as a regular SHO image but the color noise was very bad so I added a few frames of L data I had taken, layering it in as a Luminosity layer in PS. This made it possible to get good brightness without over stretching the SHO data.

Overall a successful test, and I was able to save the SSD and hard drive from the old computer!

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.
