Lagoon & Trifid wide field image (HOS)

This is a wide field view of some beautiful nebulae in Sagittarius.

I especially like the nice glow of the blobby unnamed group up top. It looks a bit like a hand reaching out from the sky! (IC 4685 would be the palm with the smaller clouds the fingers, pointing straight at us.) Or maybe it could be a well-manicured bear paw? Whatever it looks like, I'm looking forward to imaging it with a larger telescope next year -- sadly Sagittarius is now almost gone from view from our balcony.

This is my first mono narrowband image. It took me a while to process it -- I didn't care for how green it looked with the customary SHO mapping, so I went with the pleasant flame colors of HOS (the exact mix is Red: H-alpha, Green: O-III, Blue: 30% O-III, 70% S-II). I hoped to do mono drizzle integration but it produced terrible artifacts. Maybe I'll try again later.

The star colors are pretty bad. I also took a set of LRGB subframes to see if I can paste real stars on the fake nebula colors, but the result didn't look good at all -- I'll need to figure out how to isolate the stars more precisely.

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.
