2x2 Cygnus Mosaic

It took two failed nights trying to figure out mosaics, but I think it was worth persevering and I managed to capture this on my third try. Its a 2x2 and 80 mins per panel per filter. I often see less is more when it comes to processing images I am not good in that respect. Too much contrast, too much star reducing, too much noise reduction etc. However (I hope) here I feel like I have done a lot less. After stacking images in Ha I used Pixinsight image solver script, then mosaic by coordinates and finally gradient merge mosaic and the result look great. In post I completed noiseXterminator in linear and simply and lazy ran STF and went with that stretch. I used Bill Blanshan star reduction using PixelMath and completed exact same process the following day on the Oiii. I used LRGB combination tool to create a HOO palate. Finally I added the tiniest of S curves just to provide contrast and the tiniest reduction in the green chanel.

Pane1 Ha 16x300s
Pane2 Ha 16x300s
Pane3 Ha 16x300s
Pane4 Ha 16x300s

Pane1 Oiii 16x300s
Pane2 Oiii 16x300s
Pane3 Oiii 16x300s
Pane4 Oiii 16x300s

Total 10hrs 40 mins.

I am really happy with this as my first mosaic and I have definitely got the mosaic bug now.

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.
