Ok, I know it's a broad question. Let me clarify...
I'm only new to astrophotography.
In fact I've only had one session. I chose M42, and shot it with my 30D. It's my only DSLR (for now
) so I can't modify it. M42 came out with blues and reds in it. I know it's not the best shot, I overexposed the Trapezium part, will take shorter frames next time. Still learning.
Anyway, been looking around at other shots of M42 and notice that the colours of it vary widely.
Some show it mostly reds,
some more blue etc. So which one is correct?
Should i not worry so much about this when processing my images?
