I also managed to capture 3 Hrs of SII for my eta Carina nebula image.
In total this is 6.5 hrs total exposure.
I have created many variations of Eta in NB. Don't know which I like the best but I am interested to see what you think.
Captured with Atik 11002M and Baader NB filters.
Sorry I didn't mark which was which.
1 HST SII,Ha,OIII
2. Variation on shading HST
3. Reverse HST OIII,Ha,SII
4. CFHT Ha,OIII,SII
5. Ha,Ha,OIII60%,OIII100%
The images are a bit small to appreciate properly Doug. Flipping between them while they are not bad images none really grab me to be honest but this may just be because of their small size?

Can appreciate your dilemma on the colour cast.
I had real troubles processing my NB M20 until Martin Pugh re-did my data and made a far more pleasant rendering of the object. I was too heavy handed and not used to it at all and wound up with some really fluorescent images and too garish for my taste.
His processing was really well done.

Top shot Doug. Really like it. Maybe you know it, maybe you don't so here's a PS tip to get rid of these blue halos around the stars (see attached). If you go to filter>noise>reduce noise then tweak the Reduce Color Noise slider so you can dim down the rings around the saturated stars and you'll bring them back to a whiter color. I use it all the time for NB shots as depending on the blend you use at the time you end up often with purple, green or cyan stars. Nice work. You're really churning them out lately. Good for you.

Thanks for the tip Marc, Just tried it and it works a treat but it does seem to desaturate the stars a bit. I hope to get some RGB to replace the stars in the future.

Marc's solution is top notch
I've made a note of it myself to use in my images !
cheers

I like the starless one too Doug, it really shows off the nebula well!
- And better to do one now before Eta blows up, then it's going to be difficult to make a 'starless' for a while
