M17 - The Omega Nebula 6-15-20

M17 is one of those objects that has collected a lot of common names over the years. Most commonly known as the Omega Nebula, it is also known as Swan, Horseshoe and Check-Mark Nebula. As you look towards the southern sky during summer you are looking to a very bright portion of our own Milky Way Galaxy and M17 is part of that region. The Omegas nebula is large region of Hydrogen II Gas located in the constellation Sagittarius. It is between 5000 and 6000 light years from earth, and a diameter of about 15 light years. It is considered one the brightest and most massive star forming regions in our galaxy. The gas and dust associated with this nebula is estimated to be around 30,000 solar masses. A bright open cluster of young hot blue stars known as NGC 6618 is embedded in the region and the light from these stars is what caused the Hydrogen II to emit light, accounting for its strong red coloration.

I had to stay up late for this one, as it rises later in the night at this time of year and even later for me as it has to clear the trees on the east side of my driveway. I started shooting this about 1:30am in the morning. Starting just as it emerged from my trees.

This image resulted from 50 x 120 second captures. Captured with a William Optics 132 mm FLT APO scope on an IOptron CEM60 mount. Camera was a ZWO ASI294MC-Pro. Capture was done using Sequence Generator Pro and PHD2 Guiding. Processing was with DeepSky Stacker, Pixinsight, and Photoshop.

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.
