That's pretty much it Dennis.
I'm not saying I'm right, just that I think I'm right.
Some of Chris' corrections come down to "I know what I was doing at the time". Whilst I don't doubt that he thinks he knows what the scope was doing, in reality he wasn't watching it, he was obviously looking at a clear night sky (who wouldn't). Because of this he can't be absolutely certain that his scope etc was working as he thinks.
I have asked for the preceeding shot of NGC 253 that he took, that will either kill or confirm the hot pixels absolutely, if he has a long exposure picture with stars there I will stand (or in this case sit) corrected.
Unfortunately Chris seems to have followed through with his threat of walking out, which is a shame really. I'm sorry Chris (if you're still reading this thread) but it's like you've stormed off in a huff, which wasn't anyone's intention.
Cheers
Stuart
