M20's Quadruplets

It might be just me, but when I look at the Trifid Nebula, M20, I see 4 parts - my brain sees the the pink stellar nursery divided by it's dark nebula 'lanes' into four, not three? So, I'm naming this M20's Quads ;-) No matter, it's great to return to a favorite target for winter in the southern hemisphere.

This image has limited data - I had planned to shoot this to use the star colours for a narrowband project with much more data. I'm really pleased the detail I see and with the progress I feel I'm making with Pixinsight - even though I seem to re-learn some tools each time I return! There's a big improvement over the M20 image you can see that I took two years ago - new telecope, better filters and pre-processing & processing improvements

This LRGB image has some good detail in the pinkish stellar nursery and the blue reflection nebula given the limitations of my camera. It exposes the stellar jet - that wavy white line to the lower left of the massive central star lighting all this gas up for us so beautifully.

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.
