Well There are some good suggestions here, and I thank you all for your time to respond, I will work through it, with the suggestions suggested.
Paul I have suspected that they may be to high in brightness, and have followed many instructions on which way is the best way to achieve them.
Some say, use a tea shirt, some say they must be the same iso as the lights, then others say 100 iso is they way to go, DeepSky Stacker help menu say, use Av mode, and let the camera decide.
Use a light box, it just goes on, so to be truthful I don't know really which way to do it.
Gary your suggestion of custom white balance sound helpful, I will experiment with that as well.
so many thanks for your help.
Leon
