#ASIWEEK
For my 4th DSO ever, here's my take on Trifid Nebula 🙂
Constructive criticism encouraged. Praise always welcome 😉

Target: Trifid Nebula (M20) ✨
Nestled within the heart of the Milky Way, the Trifid Nebula, or M20, is a celestial masterpiece of both emission and reflection nebulae. Aptly named for its three-lobed appearance, 'Trifid' means 'divided into three parts'. Painted in hues of pink, blue, and gold, this cosmic wonder is a stunning testament to the universe's artistry. Located roughly 5,000 light-years away in the constellation Sagittarius, it's a stellar nursery where new stars are born. Its intricate structures are sculpted by the fierce radiation from newly formed stars and the shockwaves from supernova explosions

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.
