Probably the most important thing that needs to be considered before purchasing any telescope, specifically for anyone who is new to astronomy, is what you might be going to make use of the telescope for. With this in mind, it's not usually obvious that the physical properties of a telescope should be closely related to your requirements. Two of one of the most vital parameters associated with astronomical telescopes are the aperture (the diameter of the principal objective lens or mirror) along with the focal length (the distance from the objective lens or mirror to the point where the image is formed). Having a small uncomplicated mathematics, you could very easily calculate the values of these parameters to help you choose the ideal telescope for your needs.
Hadley then turned his attention to a design by James Gregory and in 1726 he produced an instrument slightly over 2" in diameter and 12" in focal length. This proved so effective that construction was undertaken by others. Notable among these was James Short, who created both Newtonians and Gregorians in good numbers, from about 1732 to the time of his death in 1768. Observatories bought his bigger instruments, a tribute to his skill, and also the smaller ones were marketed chiefly amongst the aristocracy and amateur astronomers. The principal attraction of the Gregorian style was the erect image it gave, which produced it suitable for terrestrial use. This circumstance influenced its preference over the Newtonian, notwithstanding the fact that its images should have been fairly dull. Nicely into the 19th century, having said that, the Gregorian rode a wave of popularity that no sort of telescope has known, until overwhelmed in comparatively recent years by the flood of amateurs who've flocked to Newton's style.

The focal length of the telescope is representative of either the physical 'length' of the telescope, or its optical configuration. A short focal length will give a wide field of view (the location of night sky that can be observed), with the objects in that field of view appearing modest, whereas a long focal length will give a narrow field of view, but with the objects appearing larger. The magnification of the telescope is the result of a combination of the focal length of the telescope itself, and focal length of the telescope eyepiece. A telescope of a certain focal length will generate an image of a specific size, which is fixed and won't vary. The eyepiece, effectively utilised as a microscope, then views that image. A bigger image to start with allows the eyepiece to create a greater magnification. So, by changing the eyepiece, the magnification of the telescope may also be changed.
