Pristine Widefield mosaic

This is a two panel mosaic combining the first picture that I published two days ago and a second one that fully includes IC 1848. My Manfrotto ball head was not very practical to point exactly the field in one single shot, so I finally decided to take two pictures that initially I wanted to publish separately. Finally I decided to go for my first mosaic ever and I am quite happy with the result. I hope you can enjoy it too !

In the processing I intended to reveal as much transparency as possible, to avoid the typically red "monochrome" outcome with OSCs of these nebulae. I can barely believe that this is a 135 mm (!) lens. Please look at the full version which is only 50% reduced to the original file. Amazing optics !

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.
