The Celestron MAK 90mm spotting scope boasts a generous focal length of 1250mm. This long focal length, combined with the 90mm aperture, allows for exceptional magnification and detailed views of distant objects, truly emphasizing the scope's versatility in both terrestrial and astronomical observations.
Absolutely, with a 90x magnification, one can see the major planets in our solar system fairly well. This includes observing key details such as the rings of Saturn, the moons of Jupiter and the phases of Venus. However, the level of detail and clarity will also depend on the viewing conditions and the telescope's aperture size.
The maximum practical magnification of a telescope is generally considered to be 50x per inch of aperture. Therefore, for a 90mm telescope (roughly 3.5 inches in diameter), the maximum magnification would be around 175x. However, the actual detail and clarity at this magnification will depend on the optical quality of the telescope and the viewing conditions.
The Celestron C90 spotting scope features a maximum magnification of 39x with its included 32mm eyepiece. However, this can be increased by using other eyepieces. The scope is compatible with all 1.25” mount eyepieces, allowing for a wide range of possible magnifications.

The Celestron MAK 90mm spotting scope is a remarkable blend of portability, functionality and exceptional optics.
