Thanks, doug.
Well it is better than

,excepting the coma already mentioned.
Of course, photoshop is a big help.
I am not sure how to get colour into the shot- is it just a matter of longer exposure times, hence an EQ tracking mount or barn door mount?
I am not sure if I should shoot in RAW (or RAW+JPG, at least). Will DeepSkyStacker handle RAW images from a Nikon D80?
Plus, my photoshop skills are a bit weak at the moment so stuff like colour correction, etc. needs to be studied and worked on a bit.
I have a ways to go but getting an image...it's quite addictive.
