M8 - Dive in the Lagoon

Hi ! Thanks for watching !

Final revision is a crop on M8 at native resolution , original revision is full sensor. I prefer the close-up view :-)

I found M8 really challenging to process.

First challenge was M8 brightness/contrast : the core is so bright that if you do not use HDR functions, you can not get both the nebula and the background context with a good exposition. I had never use HDR and it was a hard learning curve. Not sure I found the right spot on this M8.

Second challenge was color : I wanted to keep good stars and nebula colors. I looked at a lot of RGB M8 and did not really manage to find a reference color here on Astrobin. Found the Adam Block's version beautiful and useful to check stars and nebs colors. Mine a bit more blueish.

Third challenge was "No starless", I tried and found it difficult to go starless processing in RGB. Also I did not manage to achieve a good result using Ha as Lum so I finally created a synthetic Lum with RGB. This was used as luminance in the image. A starless Ha was used to increase core details (high pass).

I really struggled to achieve this final version (Revision BD!) and still not sure about it...

Thanks for reading !

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.
