NGC 7822 - Cosmic Question Mark (9-panel Mosaic)

“The key to all sciences is unquestionably the question mark" - Honoré de Balzac

This is a project I always wanted to start, as it's fascinating to see the universe reminding us about the unknowns out there. Long time ago my wife and I stumbled upon a beautiful image with similar framing; we liked it so much that it has been in the ending slides for most of our presentation decks where we open to questions

Finally, I have my own version!

I got lucky to have about a month of straight clear nights to work on this project. Towards the end, some unfortunate HW issues combined with non-cooperative weather slows me down/stops me from collecting more data. On average 3-4 hour worth of data per panel in narrowband domain isn't much, and the SNR suffers a bit. All in all, I'm fairly happy with what I got from a month of dedication.

Mosaic really kills patiance! Everytime I finished a project like this, I tell myself this is the last one I'd do. Till next time.

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.
