Weird results with narrowband

I'm getting washed out stacks with narrowband filter.

 

Sub attached. Looks OK, but stacked , also attached, its washed out. It isn't a matter of the stretch. I can't find a way to even dig the signal from the background.

 

66mm apo, oiii filter, 2 min subs  (I realize the two sessions didn't blend well. I'm more concerned with the washout..)

 

Stack:

Sub

 

2022 06 30 23 59 29 Oiii  1sub sample

Is there something I am missing? My LRGB stacks are all working well.

Did you use LNC and MBB to create the mosaic? You can also use the LP tool afterwards to get rid of gradients that may cause that as well.

Thanks for the reply.

 

I have however, really found the source of the problem: My dark frames. For some reason they were wiping out my signal.  Here is the same data stacked without darks.

 

I obviously need to redo my dark frames...
