Formula: Telescope Focal Length / Eyepiece Focal Length, Determine the eyepiece focal length required to achieve a particular magnification. Calculate your telescopes ability to see Saturn An Example Chart. If you use a 4.7mm eyepiece on this telescope it will yield a magnification of about 203x (to calculate magnification divide the focal length of the telescope by the focal length of the eyepiece). Multiple eyepieces … October 22, 2014, By: Kelly Beatty When we look at an object which is an infinite distance away (e.g. Furthermore we have to measure the distance from the eyepiece … You will get only two magnifications in this example, 50x magnification with 20mm eyepiece and 100x magnification with 10mm eyepiece. The eyepiece’s focal length (for example, 25mm) To find the magnification, we’ll simply divide the numbers: 1200mm / 25mm = 48x magnification That’s it! Tele Vue Optics, founded in 1977, has been thrilling amateur astronomers since 1979. By: Tony Flanders The telescope FL divided by the eyepiece FL = magnification power Example: Your telescope FL is 1000 mm and your eyepiece FL is 20 mm. Before we give you the formula on how to accurately calculate this, we need to discuss the focal length. we have a larger fiel… For example, if the eyepiece magnification is 10x and the objective lens in use has a magnification of 4x, the total magnification … October 24, 2006, By: Kelly Beatty How to calculate the magnifying power of a telescope? July 18, 2014, By: The Editors of Sky & Telescope How to Calculate Power: 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 … The Resolving Power for a telescope tells what the … The image seen in your … This calculator is designed to give the magnification characteristics for a given telescope, based on the data entered for the scope's operating specifications. Thus the 30 mm eyepiece in a 600 mm telescope produces 600/30 = 20X magnification while with the Barlow, we have 1800/30 = 60X. Formula: 2.5 X Telescope Aperture (Maximum: 350x), | Cookie Policy | Privacy Policy | Terms and Conditions | Acknowledgements | Bug Reports | Get In Touch |, First Light Optics Ltd All rights reserved © 2021, Registered Office: Unit 7 Budlake Units, Budlake Road, Marsh Barton Trading Estate, Exeter, Devon, EX2 8PY, Formula: Telescope Focal Length / Eyepiece Focal Length, Formula: Telescope Focal Length / Magnification, Formula: 2.5 X Telescope Aperture (Maximum: 350x). Thus, by calculating the magnification, you can come to a conclusion about how truly reliable your telescope is. Consider the focal length of your telescope, or telescopes, to make sure the eyepiece will provide an appropriate magnification to suit your needs. According to the manual, power, or magnification, is a function of 1) the focal length of the main telescope body and 2) the focal length of the eyepiece. Failing that, you can always visit the website of your telescope or eyepiece manufacturer. If you see any problems with this telescope calculator tool, or any of our interactive tools, please send an email to help@skyandtelescope.com. Field of View Calculator Test different telescope, camera & eyepiece combinations. The telescope magnification formula will tell you what the magnification of the telescope with a given eyepiece is. If we look at something on the horizon a long way off, we see lots of things around that object i.e. Telescope magnification is calculated by dividing the focal length of the telescope by the focal length of the eyepiece and multiplying the result by the magnitude of the Barlow lens (if using). 2: An exit pupil size (diameter of light beam as it exits eyepiece) over 7.5mm might be too large for telescope designs with central obstructions (i.e. All rights reserved. Theoretical Resolution limits for your telescope. The magnification of an astronomical telescope changes with the eyepiece used. Multiply the magnification of the lenses together. Magnification (power): The amount that a telescope enlarges its subject. Click the Calculate … 1000/20= 50x! Click on Calculate for the scope's magnification … As a rule of thumb, a telescope’s maximum useful magnification … Here is an analysis of your telescope's performance using the parameters selected above: This Week's Sky at a Glance, July 18 - 26. For example, if you have a telescope with a focal length of 1000mm and you have two eyepieces with a focal length of 10mm and 20mm, the telescope … The short answer would be that it is the power of your telescope. Click the “Calculate” button at … That is the focal length of the telescope divided by the eyepiece’s focal length. So, for this telescope… Magnification Calculator Enter the distance of the object from the lens and the distance the image is formed from the lens to determine the Magnification. It is possible to calculate how much more magnification we get with eyepiece projection over a simple prime focus setup. Factor: x : Please use the multiselector to choose your eyepieces from a selection of 1559. Zoom Eyepieces are grouped at the bottom of the list.
