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.
During the moon's quarter phases the sun and moon work at right angles, causing the bulges to cancel each other. The result is a smaller difference between high and low tides and is known as a neap tide.Neap tides are especially weak tides. They occur when the gravitational forces of the Moon and the Sun are perpendicular to one another (with respect to the Earth). Neap tides occur during quarter moons.pring tides are especially strong tides (they do not have anything to do with the season Spring). They occur when the Earth, the Sun, and the Moon are in a line. The gravitational forces of the Moon and the Sun both contribute to the tides. Spring tides occur during the full moon and the new moon.
