I had it on mirror lock for the first shot (it didn't work on multi shots though so I had to turn it off for the stat trail stacks).
I didn't use a remote until I was doing the trials
The tripod isn't the best but it was dug in to soft ground and not extended all the way.
I should have checked the manual focus instead of thinking infinity would have done!
My max exposure was only 30 seconds, should have left of longer (the ISO was at 200, should that have been 100 and a higher F number? )
And do I keep the in built noise reduction turned off in the camera?
Hopefully I'll get are better ones next time and should get something good from London.
Cheers for the pointers.
