Lagoon and Trifid Nebula

First cut at an image of the Lagoon and Trifid Nebula. The Lagoon Nebula (M8) is a giant interstellar cloud in the constellation Sagittarius and is estimated to be between 4,000-6,000 light years from the Earth. The Trifid Nebula (M20), also located in Sagittarius, about 5000 light years from earth. The data is from 18 five minute exposures, 6 each for RGB. Captured the week of 6/27/22 by staff at the iTelescope observatory in Siding Spring Observatory in Coonabarabran, New South Wales, Australia using a Takahashi TOA130 refractor telescope and SBIG STX-16803 camera. Data downloaded from iTelescope and then stacked and processed with Pixinsight, Windows, and Apple edit.

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.
