That all depends on the focal length of the telescopes objective mirror or lens, which is not
stated in the question.
Find the focal length of the main lens at the front of the tube, or the main mirror at the back.
It's printed somewhere on the telescope itself, or else on the box it came in. Make sure the
number is in millimeters, and then divide it by 30 (the focal length of your eyepiece). The answer
is the magnification you'll get with that particular eyepiece in that particular scope.
No, you can change the magnification of the telescope by simply changing the eyepiece. The two most important powers of the telescope, light-gathering power and resolving power, depend on the diameter of the telescope, but it does not control the magnification.
A Barlow lens is an accessory used in telescopes to increase the focal length, resulting in magnification of the image. It allows the telescope to achieve higher magnification without needing to switch to a higher power eyepiece. By inserting the Barlow lens between the telescope and eyepiece, it effectively doubles or triples the focal length of the telescope.
a telescope's magnification is calculated as the ratio of the focal length of the primary objective to the focal length of the eyepiece. Since a telescope is defined by the primary objective, this part of it is essentially unchangeable. Therefore, the way to increase magnification is to decrease the focal length of the eyepiece. For example, a 1000mm objective and a 25mm eyepiece yields a magnification of (1000/25) 40x. Changing the eyepiece to a 10mm eyepiece increases magnification to (1000/10) 100x.
To increase the magnification of a refracting telescope without decreasing its light-gathering power, you can use a longer focal length eyepiece. This allows for higher magnification while maintaining the same aperture size, which ensures that the telescope continues to gather light effectively. Additionally, you could also employ a focal extender or a Barlow lens, which increases magnification without affecting the aperture's ability to collect light.
The magnifying power of a telescope is the focal length of the scope in millimeters, divided by the focal length of the eyepiece in millimeters. Focal length of scope: 225cm=2250mm Focal length of eyepiece: 7.5mm 2250/7.5= 300X

The magnification, or power, at which a telescope is operating is a function of the focal length of the telescope's main (objective) lens (or primary mirror) and the focal length of the eyepiece employed.

The image in a refracting telescope appears bigger by the magnification factor provided by the telescope's eyepiece. This is typically around 50-100 times for most amateur telescopes.
That's 80 power.

The magnification of a telescope is the ratio of the effective focal length of the objective to the focal length of the eyepiece. For example, a small telescope's objective may have a focal length of 800mm. When an eyepiece with a focal length of 25mm is used, the magnification is 800/25 = 32. The term "effective focal length" refers to the focal length of the objective as affected by any "focal extender". Many telescopes are designed to have a short total size, but high power, by "folding" the optical path. A mirror-type objective with a focal length of perhaps 800mm is coupled with a smaller curved mirror that intercepts the last 200mm and extends it to 800mm, a 4x extension, so that the effective focal length of that objective is 3200mm. Use that with a 25mm eyepiece and the magnification is 3200/25 = 128. By the way, if a telescope is smaller than you are, it is seldom much use to view using a magnification greater than 50 to 100. Most objects are best viewed at relatively low powers such as 30 or so.
The magnification of a telescope M is the the focal length of the objective Fo over the focal length of the eyepiece Fe so increasing the focal length of the objective increases the magnification. The magnification of a microscope M is approximately tube length L/Fo x 25/Fe. Therefore increasing the focal length of the objective reduces the magnification.
The least important power of a telescope is likely the magnification power. While magnification allows you to zoom in on objects, other factors such as aperture size, optical quality, and clarity are more crucial for obtaining clear and detailed images.
The formula for light gathering power for telescopes is proportional to the square of the diameter of the objective lens (or mirror) of the telescope. This can be calculated using the formula: Light gathering power = (Diameter of objective lens)^2.
