Calculating Telescope Length: Refracting Telescopes

Click For Summary
SUMMARY

The length of a refracting telescope is determined by the focal length of its primary lens. In this case, with a lens diameter of 1.02 m and a focal length of 19.4 m, the telescope must be approximately 19.4 m long to achieve an image magnification of 40 times. This calculation is based on the fundamental principles of optics, specifically the relationship between focal length and magnification.

PREREQUISITES
  • Understanding of basic optics principles
  • Familiarity with telescope components and their functions
  • Knowledge of magnification calculations
  • Experience with optical formulas related to lenses
NEXT STEPS
  • Research the formula for calculating telescope length based on focal length and magnification
  • Explore the principles of lens diameter and its effect on image quality
  • Learn about different types of telescopes and their optical designs
  • Investigate resources on elementary optics for foundational knowledge
USEFUL FOR

Astronomy enthusiasts, optical engineers, students studying physics, and anyone interested in the design and functionality of refracting telescopes.

in a refracting telescope, the lens's diameter is 1.02 m and its focal length is 19.4 m.
how long must the telescope be to get an image, 40 times bigger?

i would also like to get a link to a site explaining this kind of elementary optics.

just saw the warning, please don't delete my posts :S they are in a close enough format i think..
