- UH88 is a Cassegrain reflector tube telescope with an f/10 focal ratio, supported by a large open fork equatorial mount.
- A 2× teleconverter reduces the light to 1/4, doubles the focal ratio and halves the resolution of the master lens it is connected to.
- This means the lens's F-number value is fixed to the overall designed focal ratio of the optical system (the diameter of the primary mirror divided into the focal length).
- The primary mirror array as a whole will have a focal ratio (focal length divided by diameter) of f/0.71.
- The glass plate could also break if bent enough to generate a curve for telescopes of focal ratio f/2.5 or faster.
- The "focal length" of the telescope objective is the diameter of the objective times the focal ratio.
- 7 m to a focal ratio of 3.26. The arrays are separated by 90% of their width in one direction and by just under 50% their width in the other direction.
- For example, a greater degree of barrel and pincushion distortion is tolerated in lenses that span the focal length range from wide angle to telephoto with a focal ratio of 10× or more than would be acceptable in a fixed focal length lens or a zoom lens with a lower ratio.
- Many of these targets are small and require long focal lengths, which can push the focal ratio far above [...] 5.
- Numerically large Focal ratios are said to be "long" or "slow".
- For small telescopes using spherical mirrors with focal ratios shorter than [...] , light from a distant point source (such as a star) is not all focused at the same point.
