Please enter the focal length of your telescope. To calculate your telescope magnification, you simply need to divide the focal length of the telescope by the focal length of the eyepiece mounted on it.

I’m just not sure how exactly to measure it. A 300mm focal length will have a smaller viewfield than a 10mm, although the magnification will increase with the focal length, making the object you are looking at appear larger.

A 300mm focal length will have a smaller viewfield than a 10mm, although the magnification will increase with the focal length, making the object you are looking at appear larger. Magnification = focal length of the telescope / focal length of the eyepiece this means that a larger telescope focal length, increases the magnification.

Telescope Focal Length / Eyepiece Focal Length Telescope Focal Length:

Enter the following information into the telescope calculator: It is calculated by dividing the focal length of the telescope (usually marked on the optical tube) by the focal length of the eyepiece (both in millimeters). If you enter an actual focal length and ratio then any selected.

If It's Still In The Tube, Focus The Moon On Some Semi Transparent Tape Over The Focuser.

Aperture x focal ratio focal ratio calculator calculate the focal ratio of your telescope. Now, you need to calculate the eyepiece magnification by dividing the telescope’s focal length (such as 650mm) with the eyepiece’s focal length (such as 40mm). That means that you can divide all of your focal lengths by 25 to get a rough approximation in inches.

It Is Also Known As Apparent Field Of View And Can Usually Be Found Listed In The Eyepiece Specifications.

Article > calculator input box follow the steps below to see the eyepiece table. To calculate the magnification, we just need two numbers: I’m just not sure how exactly to measure it.

Aperture In Inches (9.25 For Your Sct) * 25.4 Mm/Inch *.

It is given in degrees and will go from 40 ° to 75 °. Mm / eyepiece focal length: (1) enter any 2 of the 3 parameters for your telescope you must enter 2.

To Calculate Your Telescope Magnification, You Simply Need To Divide The Focal Length Of The Telescope By The Focal Length Of The Eyepiece Mounted On It.

If a telescope’s focal length is 1500mm, is that the distance from the primary mirror to the secondary and then to the focuser? A lens or mirror’s focal length divided by its aperture. Calculate the focal length of your telescope.
