M8 - Lagoon nebula - Bicolor

First low horizon target for this year and this one is really tough from my area. I started from 12° above horizon and ended at 15°. I think max. is usually around 16° here in Czech republic during a year. I had a hard time with processing, throw many exposures into garbage can due to imperfect stars, satelite trails etc. The atmosphere did his job also very well

So the details are not what I have expected but tried my best to get something from that data set. I call this version bicolor but truth is that data from SII filter was used for enhace the RED channel. SII channel here is unusually strong and full of structure details so I´m enclosing for the reference the final starless picture.

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.
