Take your colour image of the Moon at a low ISO number to achieve the maximum saturation levels.

Open your RGB image and produce a duplicate layer and name it ‘Desat’ - Select Layer – Duplicate Layer, type in the new name and click ‘OK’. Desaturate the duplicate layer by selecting the layer in the Layers palette then select Image – Adjustments – Desaturate. Finally, set the blending mode to Luminosity using the drop down list box in the Layers palette.

You can now select the background RGB layer and adjust the saturation and other parameters in the knowledge that the fine detail of the image is being safely retained in the Luminance channel. Once you have made changes to the RGB layer, it is often beneficial to blur this layer a little using the Gaussian Blur filter. From PhotoShop, select Filters – Blur – Gaussian Blur and select a pixel radius of between 1 and 3. Remember, the crispness and detail of the image are held in the Luminance channel so blurring the RGB layer will not destroy detail, however, some over-processing of the RGB layer can lead to unpleasant edge effects and other artefacts but the blurring of this layer can alleviate these.

Here is a slightly understated example:-

It is well worth experimenting with this technique using a range of changes to the RGB layer and making very small changes to the sharpness of the Luminance as well as this can also be very effective.

Edited for silly typo!!

I rather like your first one as it is more subtle. Having produced the Luminance layer to 'retain' the detail, you just adjust the saturation of the colour layer - you don't need to adjust the hue.

right ok how did you produce the greens in your image bare in mine the image im working with is only 1 image from ages ago soon as the moon comes round i plan to have a go at a stiched imaged

The greens were simply part of the capture - that is the colour the camera 'saw'.
