Only the last used any HDR in StarTools and even then it was a careful blend with a normal image so as not to offend the more sensitive eyes out there.
Some notes.
The contrast module seems to totally eradicate any gradients.
All images were sharpened, deconvoluted and noise reduced. All these operations do not seem to have any visible artefacts.
The images speak for themselves.

Astrograph is an Officina Stellare RH200 which has a focal length of 600mm and is F3, yes F3! Clear aperture is 200mm.
FLI Atlas Focuser.
FLI ten position filter wheel CFW-3-10 with 50mm square filters.
Astrodon E series LRGB and HA, NII, SII and OIII 3nm NB filters. Also a continuum filter 5nm.
Camera is a FLI PL16803 which has a sensor size 36.8 X 36.8 mm.
The FoV of this system is 3.5 X 3.5 degrees.
Mount is a Software Bisque PMX.
Ripper images Bert! My favourite of the bunch would be the narrowband version of NGC6164. This area of the sky is so fascinating at different wavelengths. Always something different to absorb and ponder on.
Something to consider. Given your 3 arcsec/pixel sampling I would stay away from deconvolution. Deconvolution comes into its own with oversampled data, not so much undersampled. This may lead to the stars becoming brighter which is really the opposite of what you want to achieve if presenting maximum nebulosity across wide fields. Reducing star sizes and brightness enhances large structure as the stars are less of a distraction to the viewer. Of course everyone has they own method and there is no right or wrong.
I'd also be keen to see that continuum filter given a work out. Should present stunning views of billowing nebulosity. What filter does it match, only your Ha?

Awesome Bert! Thoroughly enjoyed those results. The nebulosity is real knock-out material. Really suits your set up with a large FOV. A mosaic of the complete Vela region does in this fashion would be explosive to see.
Astounding images, Bert. I've not seen anything at all like them. Love the processing and Jase does have a point, but they are really beautiful images in all senses of the word.

You are quite correct Jase and Allan. Here is a version of Lambda Cent in Hubble NB palette with no sharpening or deconvolution.
All I did was process each NB fit independantly with StarTools and then recombined them into a tif. What is interesting is that StarTools eradicates gradients if you process this way. More on this later.
Very impressive Bert
Looks like your a fanboy of Startools and how it processes your data.keep them coming, Allan

The golden chook is growing on me, Bert. Mid tones and highlights are working well. Shadows are a touch too dark for me resulting in a higher contrast being presented. Seasoned to taste of course and if everyone's taste was the same, such images would be monotonous. So its good to see a different perspective. Keep them coming.
but how long were each of your exposures? (on average)
