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.
Around each new moon and full moon, the sun, Earth, and moon arrange themselves more or less along a line in space. Then the pull on the tides increases, because the gravity of the sun reinforces the moonâs gravity. In fact, the height of the average solar tide is about 50% the average lunar tide. Thus, at new moon or full moon, the tideâs range is at its maximum. This is the spring tide: the highest (and lowest) tide. Spring tides are not named for the season. This is spring in the sense of jump, burst forth, rise.
