How To Calculate Tube Length Of Telescope. In the example, the tube length would be 500 x 5 = 2,500 mm. Some telescopes use extra lenses and/or mirrors to create a long effective focal length in a short tube. To calculate the telescope tube length, you can use the following formula: Fe is the eyepiece's focal length. In most telescopes the focal length is roughly equal to the length of the tube. The tube length of a telescope is important to consider when making a purchase. Tube length determines the focal. For example, if the focal length of a telescope is 300mm, the tube length would be 600mm (300 x 2 = 600). Fo is the focal length of the objective (sometimes referred to the telescope focal length); Finding the tube length of a telescope is an important calculation when creating a telescope. M is the magnification of the image; For example, a telescope with a 1000mm focal length using a 10mm ocular is operating at 100x magnification (1000/10=100). Calculate the tube length by multiplying the focal length by the focal ratio. It is calculated by dividing the focal length of the telescope (usually marked on the optical tube) by the focal length of the eyepiece (both in millimeters). Once the focal length is known, you can use the following formula to calculate the tube length:

For example, a telescope with a 1000mm focal length using a 10mm ocular is operating at 100x magnification (1000/10=100). It is calculated by dividing the focal length of the telescope (usually marked on the optical tube) by the focal length of the eyepiece (both in millimeters). Calculate the tube length and magnification of a telescope lens system. Tube length determines the focal. To calculate the telescope tube length, you can use the following formula: Fe is the eyepiece's focal length. In most telescopes the focal length is roughly equal to the length of the tube. Some telescopes use extra lenses and/or mirrors to create a long effective focal length in a short tube. M = f o / f e, where: For example, if the focal length of a telescope is 300mm, the tube length would be 600mm (300 x 2 = 600).

How To Calculate Tube Length Of Telescope In the example, the tube length would be 500 x 5 = 2,500 mm. Telescope focal length / ocular focal length = magnification. It is calculated by dividing the focal length of the telescope (usually marked on the optical tube) by the focal length of the eyepiece (both in millimeters).
