LDN 673 and 684 Dark Nebulae Near Altair RASA8

I really enjoy taking on dark nebulae and dust projects. As I was looking to stellarium, I found two intriguing looking dark Nebulae.

Apparently when updating or changing my RASA set up with the ASI Air plus, I incidentally switched off dithering. This mistake left me with a fair amount of walking noise that was very challenging to try to tame without destroying detail in the dark nebulae. Definitely a good reminder to double check setting before starting projects.

LDN 673 is dense dark nebula complex in the constellation of Aquila. It stretches an estimated 7 light years across and is located 300-600 light years from Earth in the Aquila rift stretching through the middle of the Milk Way near Altair. LDN 684 is also located on the right half of the image, but find much information about it.

Description: Fixed the walking Noise, which was not caused by dithering, but was due to old darks and flats. Also, improved denoising.

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.
