Thanks guys for the imput.
Greg the images were 5 minute subs for the Luminance and 25 secs for the colour. Both you and Doug have hit the nail on the head, not enough time at the scope. I do need to check collimation. Although CCD inspector said 4" out, I think it is more than this. Focus was good as I checked this with a Bahtinov Mask and it was perfect, so I think collimation needs some work.
My previous attempts with OSC were pretty good generally but there is a lot to learn I must admit on LRGB. 10 minute subs on all and then shot subs for the core just like OSC.
I thank you for taking the time to respond. Next time I hope to have a better image.
