NGC7822 - Skull nebula - FSQ106 first light test image (John Dziuba)

NGC7822 - Skull nebula - FSQ106 first light test image

This is NGC7822, sometimes called the Skull nebula. The complex includes a single very hot and brilliant star that is over 100,000 times brighter than the sun. This single star is responsible for much of the region's luminosity.

This is first light for my new FSQ106 scope which took 18 months to be delivered. This is a test image and it has some serious flaws. But if you don't inspect it too closely, it is still a pleasing image.

As we know, astrophotography can be an immensely frustrating hobby and the gremlins have come to haunt me on Halloween. There is a significant amount of sensor tilt that I have been unable to correct. This is causing oval elongated stars and lack of fine detail in the nebula structure. The flaw is made more obvious by the full frame sensor on the ASI6200 with its small pixels. The is compounded by the RD645 focal reducer which make this a fast f3.6 380mm setup. The elongation is so bad, I was unable to use my RGB frames for the stars.

So in short while this is not an image that I am happy with from a quality standpoint, it was good practice to process it and I am learning a lot about the physics involved with the optics as I try to fix the issue.

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.
