I don’t think backgrounds should be completely black but achieving that is very dependent on the quality of your skies and data. I know for myself, shooting under B8 skies, Pulling the black point of the background is sometimes the only way to get rid of the low frequency gunk that lurks there. I also don’t think that background brightness needs to go too far. A value of around 15 is enough. You want it up a bit just so as not to destroy the very faintest of detail in an image. It’s a dance to be sure.

something around 20 measured with the little pipette thing in photoshop or affinity.
i like adding a layer (photoshop / affinity) colored in my target value, inject some noice (similar to my picture) and add it so that no area within my picture has any darker spots
Depends on the subject
Galaxy with few background things - dark
nebula with lots going on - light
In the examples given, I prefer the brighter and voted accordingly.
But it comes down to a matter of taste, or sometimes a lack there of.
I don’t dabble or try to make a silk purse out of a sows ear. I’m a Post Processing minimalist. I want what my camera see’s, not some tooty-fruity Skittles rendition.
But that is just me.

These both look dark to me :)
The darker one and you can probably push your data even further in the stretching
The background level that we all perceive will vary with variations between monitors and room lighting. The better question to ask is, “What should the background level be for a galaxy image?” So, have you looked at this presentation?

The guy who gave this talk goes into some detail about how to get the background right for a galaxy image with respect to the color and the brightness level.

Hugely depends on viewing device. On my monitor I will process a perfect background with the correct ADU value but when I view that image on my phone or iPad it looks horrendously bright, so I often make two versions

I’m generally setting galaxy background a little lower, around 0.08-0.09 average. Nebula fields are brighter, at least 0.15 or more depending on the target. Some variability exists depending on target but in general for me galaxies a little draker than nebulae.

The “bright” one seems to be showing more information and looks way more natural.

Both of these are too dark.
That’s an excellent question—one I’ve asked myself countless times as a complete beginner. In my opinion, it’s also a matter of personal taste! Recently, I was thrilled to have achieved what I considered a much better processing result on the Nebula Headphones, but a more experienced amateur astronomer friend told me, “The background is too dark!” And I still like the image with the dark background! Finally I uploaded both of them in my gallery as different versions.

Advice needed on hard printing of a specific image
I’m looking for an advice to order a print of an image that you can hang on a wall. I wanted to print few images from time to time as a gift but did not feel like printing a version of traditional DSO object would be a unique enough. There are millio...

Imaging narrowband versus a 'darker' sky location.
Hi all, If I am imaging with 3nm filters (either mono or OSC) say from a Bortle 6 location - no moon (my garden). Would using the same filters/cameras in a Bortle 4 location provide much better data, worth travelling to…. or would it not be really as...
