IC 5146 Cocoon Nebula HaRGB

Same as many, clouds, fog and smoke have severely affected my imaging opportunities over the last 3 months but August gave me two clear nights. Captured using Ha,R,G,B filters in my Bortle 6 sky and processed using a combination of StarTools and Pixinsight I have not really been able to showcase the dark dusty portions of this nebula with only about 7hrs of data at f/10, but at least I got an image. I am hopeful that I can add more data in the future to enhance my image.

Process steps PI and ST:
Calibration, crop, ABE - PI
Synthetic L from the R,G,B - ST
R+Ha - ST
Combine the syntheticL+newR+G+B - ST
Standard ST workflow to stretch and process the data emphasizing star profiles and colors.
Starnet star mask and then stretch (with stars masked) to enhance nebula - PI
Final contrast, saturation tweaks and crop - PI

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.
