After some constructive advice or criticism from Greg Bradley, I looked into doing something about the stars in my Vela SNR mosaic.
I came across this method for removing stars that is a .atn file you insert into Photoshop.

After a lot of experimentation here is just the narrow band data without stars 2.5MB

Here is a medium image of the colour data stars combined with the starless NB data 3.5MB

Below are the original mosaic, the starless NB and the new version.
For very faint nebula I think Greg's advice was spot on.
With better data this would be even more spectacular.
