Swimming With The Swan In A Clear, Dark Sea (M17)

Since taking up astrophotography last year, I've been particularly excited about my family's annual summer trips to the beach in North Carolina. The area's Bortle 4 skies treat the unaided eye to a beautiful view of the Milky Way, and the house we rent offers an unobstructed view of the southern sky that I can only dream of from home.

I was determined to make the most of the time I have in NC, so I have been planning out my imaging sessions for months, and I settled on the bright and beautiful Swan Nebula (M17) as my first target. It was clear the moment I arrived that that first night would be perfect for imaging, so I quickly unpacked and reassembled my gear. Given the clear, dark skies, I decided to capture only broadband data, and even decided to do without my trusty Optolong L-Pro light pollution filter. Instead, I purchased an Optolong IR/UV cut filter for the occasion--and it performed admirably. I spent an enjoyable night contemplating the Milky Way and tracing constellations while my "C6 RASA" collected data beside me.

Although late June nights are short, I managed to collect 5.5 hours of data on the Swan. Each subframe was clear and bright; the processed stack needed only modest post-processing. I am thrilled with this image and I hope you enjoy 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.
