THE MISSING CHANNEL

My previous version of this picture was from a session I had under the dark sky of Casera Razzo at 1700mt above the sea level (Bortle 3), two hours far from home. At that time (2021) I just took the RGBs for this object and I was pretty satisfied with it, thinking I did the right thing going there stay out for the night, sleeping in my car to pick the frames up. I came back with 12x600" frames for each RGB channel and it was good. It was really good to me.
But I wasn't right, it wasn't enough. So I started to brood and overthink at this picture. Surely the L channel was the missing one. I know it, I'm perfectly aware of it. It's not a mystery that L should have been the one I had to get to give detail to the picture. But I didn't ever try this at home (they usually say "don't try this at home!") since they always said that it would have been a waste of time from a light polluted sky. But I couldn't get there, I had no chance to get to my favorite Bortle 3 location again to do it.
It was a challenge since my backyard is heavily light polluted by street lamps. So what? I found it. I found how to get it. I made the math and found that 67,8s for each L frame was the right exposure time considering my camera specs and light pollution all around my backyard. I added 9,6 hrs in L.
To be honest I didn't expect such a result, but definitely planning and calculate were the right choices to me.
And doing so I'm now able to tell that the missing L channel can be acquired even in a light polluted area (Bortle 5) if you plan and calculate. Definitely: "you can do it at home".

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.
