[g__day (Matthew)]

I was wondering why my shots of say the NGC 2070 have a definite blue green tinge to them - whilst the stars in the shots look white?

I am learning how to re-balance the colour and I can understand how a filter might affect how much light gets through of a certain frequency, or how a DSLR CMOS might be more sensitive to Blue than Red.

But what I don't understand is why if the colours are wrong are the stars white? Is it because the higher intensity light is correct, but the fainter light is blue / green shifted?

In Photoshop CS2 - what is the best editting technique to restore proper colour balance please?

Many thanks,

Matthew
