I thought I'd add another post to continue the pseudocolour mapping discussion started by Peter in
this post. I found a colour mapping scheme developed for astronomy by Dr Dave Green from the Battcock Centre for Experimental Astrophysics at the University of Cambridge. It seemed like a good idea for a PixInsight plugin which I've written and placed on
Github along with a short explanantion of the algorithm.
Use of the plugin is pretty straight forward. It can only be applied to a monochrome image (using it on a colour image makes no sense). After selecting the source image, the parameters can be changed (explanation of the params at the Github site) and clicking the 'Apply' button updates the colour scale and the pseudo colour image. This can repeated as many times as you like. When happy with the results, the OK button completes the process.
I've attached an image of the UI together with an example performed on the Horsehead.
I encourage people to download it and play with it and would love to hear comments from anyone using PixInsight (especially if there are any bugs!).
Thanks, Kevin
