Hi Nik,
a wonderful sharp image but I don't know about the processing.
Where did all the O3 blue go as per here:

It was a different focal length and I couldnt get the blues out at all for some reason, still learning remember it's the L-Extreme and an OSC

[alpal]

OK sorry -
so the L-Extreme filter is allowing the Blue light to enter

but the One Shot Color has a Bayer Matrix which
is only picking it up on 1 pixel out of 4.

Yep IT's a work in progress one day I'll go mono but not for quite a while

Finger-lickin' good Nik!

Looking great! Super tight and I actually don't mind the colour pallet... I'm interested how did you created the synth green channel in APP tho?

[Nikolas]

Hi Dave, in APP when you stack you have the option of selecting mono HO111 under the bayer matrix and use the final result as the synthetic sulphur/green channel, then you obviously play around in combination setting and adjust to suit
this video (https://www.youtube.com/watch?v=jO7QnSAz5Cc) and the next one (https://www.youtube.com/watch?v=52N4kJfUSno) helps explain

[Nikolas]

I changed up the processing using just HOO and a smidge of synthetic sulphur and this is the final result.

It looks great Nik
The rich orange, blue and violet really works.:thumbsup:

Best
