Tonight, I took my first image of the Moon with my QHY10 camera/Equinox 80mm telescope.
The image should colour dispersion. I do have a dispersion corrector but it is 1.25 inch fitting and the QHY10 camera is definitely 2 inch fitting.
I found that this problem can be addressed using GIMP2 software – in this software there is a function called decomposition – this splits a colour image into separate individual RGB images.
I have described the process I followed in GIMP2 to decompose images below.

Selecting RGB in decompose:
Decompose in GIMP2 results in 3 separate layers for each colour – each image is presented greyscale & can be saved:
