Veil Nebula - RGB + HaOIII - 9 Panel Mosaic - 11K x 11K

Biggest project yet with the tandem set up and longest in duration for me. 9 panel mosaic (3x3) of Veil Nebula complex in Cygnus. Taken over June/July with no complete astronomical darkness (typically imaging from 11:30pm to 2:30am during nautical darkness). Tried to take 20 minute frames for narrowband using the G4 whilst the ASI2600 took RGB in 5 minute intervals, moving to the next panel and repeating.

Aligning, merging and processing 1GB individual mosaic files (and masks) was a challenge!

Although I managed to capture 2hrs per panel in Ha, weather only allowed 1hr or so for OIII which is noticeably noisier. I am happy I managed to complete this project though - and that is over!

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.
