Cocoon Nebula with Dust Trails Sh2-125 Ha+OSC RASA8

I had not taken a single sub frame of the Cocoon Nebula prior to this effort. I was quite shocked when I realized that I had missed it the last few summers. I used the RASA with OSC color and used Ha a luminance layer for the cocoon itself. In version C, I used the Ha for an enhancement layer. I enjoyed the image more without the Ha enhancement as it was distracting from the dark dust trails. I found finding the right stars size to be tricky in order to emphasize the seas of stars versus the dark structure of the dust tails.

I shot the Ha layer in 1x1 binning (2.3um) with the 294 MM which provider decent resolution for the cocoon it self. This young stellar nursery is 15 light years across and located 3.3K light years from Earth with the Cygnus Constellation.

Hope you enjoy!

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.
