Thanks Clive.

Yes-at last!,all of sudden it all just seemed to starting guiding,Think slightly de focusing the guide star may have been the last piece of the jig saw to fall into place.

Ok,what is bayer? I did stack and dark frame subtract,it worked well-niffty program.Is bayer something to do with colour-this image seems very Black and White.

Thanks for advice-Chris
