If anyone's suffering from some cloudy nights and looking for something to do, I've made available my recent Ha and OIII integrations of NGC6188 as 16-bit fits. I think there's a touch over 7hrs of data there.
I'm keen to see what the everyone else is able to do with this data, because I'm a total newbie when it comes to narrowband processing.
Nice work guys! If you don't mind posting the software used to process the images and a quick run down on what you did, that'd be quite helpful to myself and others I imagine.

I used Pixelmath in PixInsight to combine the images, then ABE, BackgroundNeutralization and then HistogramTransformation--nothing fancy. You could also use Curves to saturate a bit more

Thanks mate!

Nice data Lee!
Cheers Lewis! Nice work; I prefer the more traditional look too. Mind posting software / processing details?
OK, so I felt obliged to go a bit over the top and do something a little different since we had plenty of more traditional treatments
Using PixInsight: I blended the Ha and Oiii to make a Luminance. I mangled the Ha to red/orange tones using PixelMath and CIE Lch channel combination then used the Oiii as a mask and added some blue with CurvesTransformation. I stretched the Lum and colour, did a small star reduction and combined them. Then I tweaked the contrast a bit with LHE and HDRMT...

This is probably the first time that I've ever really tried using PI. Actually only the second time that I have had something other than JPG files to play with in it so I have probably gone a little overboard mind you!!
Ha - Red
Ha+OIII - Green
OIII - Blue
Played around with the saturation and curves, slightly decreased the overall blue response, especially after slightly increasing the saturation, stars got a bit too blue. Ran a reasonably weak denoise and then an UnSharpMask.
Wanted to go a little left of field colour wise to everyone else. By no means natural but I like the green.
Edit: Possibly shouldn't have tried to flatten the field quite so much though, destroyed the lower left corner a bit :/

Nice work Rick! Interesting process there using OIII as a mask for introducing blue; wouldn't have thought of that.

Nice work, Colin, good to see something a little different. Good work especially seeing it was your first time using PI. Try using deconvolution rather than USM; when you can get the right parameters it works rather nicely.

...ahhh......wha? OH, nooow I know what you mean, of course ..yeees, I see....
Interesing to see all the different takes (including the mandatory Lewis/Magenta/Sidonio reference version )
