Info:
I have 17h30m of November but only in the central region of M78, I discovered LDN1630 in some Astrobin images, so I knew that LDN 1630 extends all the way to the Horsehead Nebula. And he decided to go crazy and do a 17h mosaic from the top and bottom of the Messier 78 regions to get a good shot of the dark nebulae in the region and in the center of the M78 region the integration reaches 34 hours, and The smallest photographed portion of the mosaic is 16h54m in the upper region. It takes a few tricks here and there to integrate the three parts into one and then edit them. This is the longest challenge and integration project so far and I am so happy with the result that I ended up ordering a print in ultra-smooth and metallic prints. As always, the bar that the community has for 2023 has been so high and honored to share my work from my home and modest scope.

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.
