What will decreasing a telescope's eyepiece focal length?
The magnification of the telescope image is(focal length of the objective) divided by (focal length of the eyepiece).The focal length of the objective is fixed.Decreasing the focal length of the eyepiece increases the magnification of the image.(But it also makes the image dimmer.)
If the primary mirror of a telescope have a focal length of 225 centimeters and the eyepiece has a focal length of 7.5 millimeters then what is the magnifying power of the telescope?
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
Telescope magnification power with a 30 mm eyepiece for a telescope?
To calculate the magnification power with a 30 mm eyepiece, you need to divide the focal length of the telescope by the focal length of the eyepiece. For example, if the telescope has a focal length of 600 mm and you use a 30 mm eyepiece, the magnification would be 20x (600 mm / 30 mm = 20x).
How can the magnifying power of a telescope be increased?
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.
Show How to calculate the magnification of a telescope with a 1000mm focal length an8-inch primary mirror a 4-foot body tube and a 25 mm eyepiece?
The apparent magnification of telescope optics is(focal length of the objective) / (focal length of the eyepiece)= (1,000 / 25) = 40 .The diameter of the primary mirror has no effect on the apparent magnification.The length of the body tube is involved in the case of the Newtonian configuration,only because it has to be long enough to hold the eyepiece in the right place.

What is the formula for calculating the angular magnification of a telescope?
The formula for calculating the angular magnification of a telescope is: Magnification focal length of the objective lens / focal length of the eyepiece.

What is the power of the eyepiece?
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.
Telescope magnification power with a 30 mm eyepiece for a telescope?
To calculate the magnification power with a 30 mm eyepiece, you need to divide the focal length of the telescope by the focal length of the eyepiece. For example, if the telescope has a focal length of 600 mm and you use a 30 mm eyepiece, the magnification would be 20x (600 mm / 30 mm = 20x).
How does the eyepiece affect the total magnifacation in a telescope?
A telescope consists of two lenses. 1) The main lens which collects the light ( it is relatively bigger that eyepiece). 2) Eye piece , through which we see. Magnification of a telescope depends on the focal length of the eye piece and the main lens. Magnification = Focal length of the main lens / Focal length of the eyepiece . For example : If the focal length of the main lens is 12 units and the focal length of the eyepiece is 2 units , then the magnification will be 12/2 = 6.When the focal length of the main lens is constant , the focal length of the eyepiece is inversely proportional to the magnification.

What is the focal length of a telescope's mirror if I use an eyepiece with a focal length of 26 mm and I get a magnification of 70x?
The focal length of the telescope's mirror can be calculated using the formula: Telescope focal length = Eyepiece focal length × Magnification = 26 mm × 70x = 1820 mm Therefore, the focal length of the telescope's mirror would be 1820 mm.
What happens if you decrease a telescopes eyepiece focal length?
The magnification of the telescope image is(focal length of the objective) divided by (focal length of the eyepiece).The focal length of the objective is fixed.Decreasing the focal length of the eyepiece increases the magnification of the image.(But it also makes the image dimmer.)
What is a barlow lens on a telescope?
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.
If a telescope has an objective with a focal length of 50 centimeters and an eyepiece with a focal length of 25 millimeter what will be the magnification?
