EDIT: The revision includes a greater stretch of the Ha data compared to the first. I think this is the best balance between the contrast of the elements of the field and the amount of Ha in the area. If I stretch the Ha to its full extent...not much is added but a red bias. (I *think* I am happy now. lol )

This is an HOO rendering of  WR 134 and its surrounding nebulosity. 
The data was generously provided by Frederic Germain. 
The processing steps are outlined in the new narrowband FastTrack Training course I am putting together.
Here is the thing- I process NB images like I do broadband images. So I think my choices lead me to places that fit my style, and then I look at others and perhaps I second guess myself- but I really do like this rendering. To me it tells a story of the field. You can see great mounds of nebulosity that are in the foreground with wind blown wisps beyond. I also I I I think this orientation does better to draw the eye to areas of the image with the rising pillar of red in contrast to all the business beneath. I
In this particular case the use of ImageBlend in combination with SelectiveColor (script) did most of the work after NarrowbandNormalization.
RGB stars were also blended in- but they take a backseat to everything else.

Frederic did acquire SII as well. It is pretty weak and mostly overlaps with the Ha- but I will likely come back and produce the HSO version of this field. 
But the point of this image was to demonstrate HOO processing (because this leads to dual flter processing...).
