NOOOOOOO DUNCAN! COME BACK TO THE LIGHT!!!
Don't cross over to the dark side! You will
never return (with your wallet intact)
Now, having said all that, for your first go, WHAT A CRACKER!
Yes I know it could be better etc etc, but jeez, thats a corker for a first effort! Well done!
Stars look good to me and overall its a beauty.
I will leave the technical improvements to those better suited to advise you with what to do properly, but to my newbie-never-before-tried-a-DSO-pic-eyes, thats a fantastic start.
Well done
Cheers
Chris
