M17 (Omega or Swan Nebula)

25 years ago, I planted 16 arborvitae trees as a wind break along the western edge of my property ... they've since grown to over 14m tall. Today, they are 100% effectiveness as a wind break and a barrier for astrophotography of any targets within 25° above the horizon to the southwest and west. To see if I could image M17, I moved my scope from its normal location in center of my back yard to the northwest corner of my yard, which is right up agains my neighbor's fence. It was a damp and thorn-invested location, but provided about 2-3 hrs of unobstructed imaging time between 10 pm and 12:30 am.

I was thrilled to collect 67 frames at 180s each (many more were ruined by clouds or rooftops) over three nights ... the skies were mostly clear and moonless. It's been a tough summer — we've had exceptionally smokey skies and rainy for much the past three months. The rain has revived our aquifers, wetlands and ponds, to which I am grateful. However, it's made it very difficult to get multiple nights on one target.

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.
