Here is a quick and easy method to focus a camera lens on stars in the night sky. If your eyes are not as good as they once were, this method might help. The key to focusing a camera on stars begins with a few simple rules. First, set your camera and lens to full Manual mode and manual focus. Point your lens at a very bright star. Then use Liveview mode and your camera's focus magnifier to zoom in for a closer view while focusing.
Spring Tides occur during two phases, full and new moon. This is because the moon earth and sun are aligned during both of these phases. It is opposite during neap tide, in whâ¦ich the moon and sun meet at a right angle on earth, which means the moon during neap tide is at the first or third (last) quarter phase.
Tides occur because of the pull of gravity of the Moon and the Sun on the Earth's oceans. Because the Moon is closer to the Earth, it has the greatest effect on our tides. There are approximately 2 high tides and 2 low tides every 24 hours. Spring tides (often called 'king tides' by fishermen) occur at New Moon and Full Moon when the Sun, the Moon and the Earth are in line.
