Dark Arches in the Perseus Molecular Cloud : LDN 1448

Lynds 1448 or Barnard 203 is a dark nebula, situated South-West from its more famous neighbour, NGC 1333. It is part of the gigantic molecular cloud in Perseus, located at around 1000 l.y. from Earth. The cloud contains over 10,000 solar masses of gas and dust covering an area of 6 by 2 degrees (Source: Wikipedia). These beautiful and dynamic dark clouds also contain Herbig-Haro objects, illuminated by proto-stars.

This sky region is one of my favorites, together with the dark nebulae in Taurus. Processing it was a long process, I had to retake flats and flat darks multiples times because of some unexplained gradients (it was an occasion to test the new Gradient Correction Tool in Pixinsight). Took me a week of trial and error, I had to start from scratch multiple times. I carefully verified the color calibration with SPCC and only global transformations were applied in order to maintain the balance. I think it's a fair rendition of this region and the best I could produce after feeling at first that the whole project was lost due to calibration issues. Hope you like it.

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.
