This was my first real success in a longish exposure. Previously I could only manage a 60sec exposure before the stars started trailing.
Problems I over come were; Setting up the tripod so it was horizontally flat and pointing south correctly, guiding with PHD and setting the GPS and time accurately.
Image has no processing done at all.
