"Starless' Vela SNR

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.

http://astroanarchy.blogspot.com/200...ps-action.html

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

A larger version here 23MB

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.

Middle one has the punch as the o3 data jumps out more
Might just change the color balance of the green area ( upper left to a more bluer balance perhaps.)
Nice work.

Love #2 as well. The Oiii really pops up and adds to the blend in #3. Really nice rendition.

A clever idia, it allows the nebula that is always there to really show itself. Sometimes stars are a real nuisance

Yes Scott most folks do not realize how dim these nebula are.
