Thanks guys. I won't be doing anything for the next few days, as I'm coming down with something, and even looking at the computer screen hurts at the moment
I'm on firmware 1.02, so I don't think that's an issue.

1) What ISO setting and what aperture did you use? You should - at least for your first attemtps - have your lens wide open and an ISO setting of 1600. Further, you should be prepared for a bit of post processing. Your camera may have recorded (much) more than you would know from first sight. I may immodestly refer to my own little tutorials here:
About Astrophotography - and Light Pollution (I) and here:
Camera Settings for Astrophotography
2) What batteries did you use. Keeping the aperture open for an extended time requires batteries of high quality. I never had problems with non-rechargeable lithium energizers, nor rechargeable eneloops, (on my K200D).
Thanks for the links, I'll have a look at them when I'm feeling a bit better
Looks like I got myself a bit confused somewhere along the lines - I was using an ISO setting of 200!
On the 30s shot, I had the lens set to f4 and at 70mm, although the EXIF data says it was 250mm (which is longer than the lens). That shot came out ok, but not great, but at least now I know where I went wrong!
I used 2900 mAh rechargeable Ni-MH batteries from
7dayshop.com. I don't think they were the problem though, as I've had comparable results to my Eneloops, and have had no problems shooting video with them. I think I've probably just missed a setting somewhere.
I've attached the 30s shot and a crop if that helps. The crop made me realise how much wind there was last night though. I was wrapped up in so many layers, I couldn't feel it. Either that, or there are dozens of small horsehead nebulae out there!
