Hi all,
I just published a new script (for Pixinsight) to convert Osc dual band images in RGB format to a HaOO image. I used the script to process  this image https://www.astrobin.com/4zy08q/.  

 If you would like to download it, then you can find it here:

Gave it a shot on a heart nebula crop of mine.  Flawless script!

Nice! Thanks for sharing. I do all this manually in PI by separating the channels and then combining to make new ones etc. (for example this image) So I shall try your script out and see how it compares

I'm new at the dual-band filter stuff and there is lots to learn. The few images i tried processing, invariably ended up quite uniform in color.
I think I understand what the script does and i'm aware of the possibilities, but i never attempted to perform these actions manually.

So I tried this script and it magically adds a lot color depth to the image! 

There is a lot to investigate, but I'm already sure i'll be using this often. Thanks a lot for sharing this!

I haven't tried the script but have many PixelMath expressions saved to do similar things.  I'm curious about how OIII is built in the script though.  You're using "max(Green,Blue)".  I've used "Green*2/3+Blue/3" because of the bayer matrix, 2 green for every 1 blue.  Given the overlap of green and blue this seems a more true translation of the dual-band data.  Have you tried this instead of max of the two channels?  I will have to go try out max sometime this weekend, and this script.  Thank you for sharing smile

Hi,
I have tried different ratios of blue and green. But, I favor max(blue,green) to gather the O III data. I may add the ability to select between the two options in a future version. I really appreciate your input. 

Thanks

Paul
