My first LRGB Of M51

I'd argue with that tutorial on the basis that the RGB image is processed the same as the luminance. I try to stick to linear histogram adjustments and use curves only as a last resort. Have you got Noel Carbonis actions for CS? Good for removing colour gradients which you will get on long exposures due to change in sky background

Hi Kieran,

Ok I trust you:>)) I won't do it his way. I do have the the actions in Photoshop I'll play around with them and see what happens. Thanks mate

Carl.
