My first attempt at creating a mosaic: this image is the composition of 9 panels (3x3) taken with a planetary camera (the uncooled ZWO 178mc with very small pixels). It was very hard to manage the noise and the different background brightness I've got on each panel, some of them were very different, but it was a good opportunity for me to dig into the tools to be used to create panels.

By the way, the field is amazing and extremely populated of stars, the final result still impress me when I look at the hole picture.

Due to the over-sampling scale (0.7arcsec)v the image was processed at his natural scale and finally downscaled 2x.

Hope you enjEnjoy

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.
