LDN 1495 is a “Dark Nebula,” whereas LBN 782 is a “Bright Nebula,” the blue reflection nebula right of center, and LDN 1495 is the greater extent of the brown-red dusty patch that dominates the image. As with all complex cloud images, it seems some features have multiple names, and some are left unnamed. The names of bright clouds, for instance, commonly assume the name of the cluster of stars that illuminates them. Commonly, those clusters consist of newly formed stars and are concealed from sight (at least in the visible spectrum) by the clouds that feed them.

This is another reprocessing adventure. My first pass on these data dates from 2018. Looking at that earlier attempt, I take some pride in having progressed—progressed enough to have deleted that earlier version from Astrobin. Maybe someday, this one too will be relegated to the trash in favor of an improved version. The big struggle for me is the stars. I process the images rather intensely. The stars are so different from the nebula that keeping the stars nice and round and small while stretching and coloring the nebula to the extent I favor has thus far befuddled me.StarNet doesn’t do the job…it harvests too much halo around the stars that processing turns into ridges and halos, and masks never fit all star sizes, just snuggly enough but no more so. For now, "damn the stars…full processing ahead! "

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.
