How are you focusing the camera? Most modern lenses can go past infinity. I have seen people use a focus mask and tape the focus ring. Also, how long were the exposures. I presume you're unguided with these?

Thanks, David. I focused manually on a bright star just looking for the tightest pinpoint. It looked best when the focus mark was right in the middle of the infinity symbol (as you said, it was possible to turn the ring past this spot). Yes, all unguided. The Crux exposures were 15 secs and the Omega ones were 5 secs. At 300mm the lack of polar alignment was obvious in longer exposures. That's my next challenge!

I had a quick play in CS4 with your Crux shot and managed to squeeze some colour out of it.

Thanks, Dennis. That's very cool. What did you do? I'm not really au fait with PS yet.
Cheers,
Rick.
