Thanks for your comment Mike.
I used a star reduction in ImagesPlus......I have redone this image without the process you mentioned...all I have done is split the channel and ticked the luminance box in IP which gives me a grey scale image.....then used digital development keeping an eye on the histogram so I dont clip it too much...then sent to PS for slight level and curve changes...I also ran this through some very minor noiseware....but no star reduction used.
You can clearly see the stars are larger then my original...is this any better Mike...I really dont know any techniques enhancing grey scale images then what I normaly do with color images.
