This is the final entry in the Summer of Darkness - though the acquisition extended a bit into autumn. This is another one where there turned out to be a lot more going on in the frame than I expected. This turned out to be a lot of fun to process though it brings me up against the limits of the data and the tools as the extreme stretch required to bring out the fainter parts of the dust also brings out some horrendous halo artifacts. I was able to (more or less) tame them though some residual halo crud remains (but it's a lot better than it was!).

This is also another one that shows just how deep amateur images are today compared to the plates they used when these catalogs were defined. LDN 1295 is just a fraction of the cloud it is a part of and the same is true of 1296. But, regardless of the catalogs, it's a fascinating region!.

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.
