M20 - Trifid Nebula is a famous star-forming region located in the north-west of Sagittarius in a star-forming region in the Milky Way's Scutum-Centaurus Arm in our southern sky.

The name Trifid refers to its three-lobed appearance. Messier 20 consists of several different objects: an emission nebula, a reflection nebula, a dark nebula and an open star cluster.

The dark nebula consists of dust clouds that absorb and block light from the bright objects behind them. It is responsible for the apparent gaps in the larger emission nebula that give M20 its trifurcated look. The other two types of nebulae – emission and reflection – make M20 glow in different colors in images.

This photograph consists of 6 hours of exposures from 96 images taken with a Skywatcher esprit 120ED telescope and the ZWO ASI2600mc camera riding a Skywatcher EQ6r Pro mount using a ZWO OAG & ASI290mm mini guide camera.

Image acquisition managed by Astrophotography Tool (APT) with guiding by PHD2 running on an Intel NUC from my rural driveway.

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.
