As a result, the eyepiece you use with it will not work at its native focal length, but at twice that. This actually increases magnification for the same eyepiece.\n  <\/p>\n<h3>Calculation example<\/h3>\n<p>\n    For example, if you have a telescope with a focal length of 1000mm and an eyepiece of 25 mm, then you have a magnification of 1000\/25 = 40 times. Now, if you add a barlow to your telescope, the focal length is no longer 1000mm but 2000mm! If we repeat the calculation, we get a magnification of 2000\/25 = 80 times.\n  <\/p>\n<h3>Advantages of the Barlow<\/h3>\n<p>\n    So, with the same eyepiece, you can vary the magnification of your optical set. That's the whole point of having a barlow. As such, you can double your range of eyepieces!\n  <\/p>\n<h3>Explore Scientific Barlows quality<\/h3>\n<p>\n    Explore Scientific barlows are excellent. Thanks to an ingenious four-lens system, they offer exceptional image quality across the entire field of vision. Perfect for observing, they can also be used for photography!\n  <\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Principe de la Barlow Le principe d&rsquo;une barlow est de multiplier la focale de votre instrument.
