Nice image Rowland. Overall very nice.
Yes the colours around Antares should be more yellow but still good.
A bit of coma showing in the stars when you zoom into the corners. Did you stop down your lens a couple of F stops or did you take the shot wide open? Most commercial lenses require knocking them down a couple of stops. I am going through the same thing imaging with a CCD and some Pentax lenses.
Also there was a thread here recently I think from Marc about aperture rings. As I recall it mentioned that they can stop the multi spikes on the bright stars that come from the Iris mechanism in the lenses.
I'd like to find out more about that if that works as again I would like to prevent that with my own lenses.
A great shot of a fabulous area of the sky.
Greg.
