LDN839 & (a lot of) friends

After months of clouds, we finally see a hole in the clouds, and planned a project between brothers.
So we looked for a rare imaged region, with some voluntary diffculty, and we found the very beautiful nebulosity of LDN839, which start in O and continue in H.
We decided to shoot them after some researchs on the field to get a nice view of the region.
After the 2 first nights, we discovered the very faint signal linking LDN839 and LBN156 (above), and decided to got a maximum of H and O as much as possible.

The processing was very difficult to respect each object, since we knew before that a lot of nebulosities (NGC6857) was present, but also, we discover a lot of PN in the field!
We therefore took the time to process the image and learnt a lot of things to preserve details and give a way to include a maximum of stars without altering the nebulosities, and get a nice balance between.
On the left top, you can find the PN named "Ch1", discovered in 2017. We discovered the very faint signal of this PN during the processing of HOO image, and contacted Pascal Le Dû to share this discovery. He confirmed to us that the PN was already discovered, but the signal was indeed very interresting.
We never seen before "Ch1", and we hope that our image is the first and best image of this PN, since the goal of the image was not to show it :-).
After a lot of tries, this is our final image for this time!

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.
