so i am building a refractor telescope and i don't know what size to make the tube and what material to use for it?
please telll me this is a huge % on my grade

A focal point in a telescope is the point where all incoming light rays converge after being reflected or refracted by the telescope's optical system. It is the point where the image of the observed object is formed.
The focal point in a telescope is determined by the curvature and positioning of the telescope's mirrors or lenses. The shape and distance of these components determine the convergence of light rays at a specific point, known as the focal point.
The focal point is the specific point where light rays converge after passing through a telescope's optical system, while the focal length is the distance between the center of the lens or mirror and the focal point. In other words, the focal length is the distance from the lens or mirror to the focal point.
Yes, the focal point of a telescope can be adjusted by changing the distance between the optical components, such as the lenses or mirrors. This allows for the image to be focused and adjusted for different viewing conditions.
The focal point of a telescope plays a crucial role in determining its magnification. A shorter focal length results in a larger magnification, while a longer focal length leads to a smaller magnification. This is because a shorter focal length will bring the image closer to the eyepiece, making it appear larger.
