Cocoon Nebula (IC 5146)

Cocoon Nebula (IC 5146). I feel like I've finally got everything dialed in on my Askar FRA500 set-up. I installed an EAF, added some much-needed dew strips, and neatened up the cables a bit. (I won't dwell on the night a couple weeks ago when a cable snag ruined my night--and almost the mount as well.) At the same time, some wildfire smoke notwithstanding, the weather has been improving, and I've had a pretty successful couple months. So it was a real delight to spend two fine summer evenings collecting about 10 hours of clean broadband data for this image of the Cocoon Nebula (IC 5146). I love the result (especially in comparison to my first Cocoon image, see below), and I feel like I'm finally in a groove!

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.
