WHICH MAGNIFICATION?- SELECTING THECORRECT EYEPIECE The optimum magnification depends on what you are looking at.As a rule of thumb, the best image results from using a magnification, whichis not more than 1.5X – 2.0X the diameter of the objective lens. Forobservation of moss heavenly bodies, a magnification of 75X – 100X can beachieved with a 50mm objective lens. A lower magnification should be used forthe observation of the stars. This provides a wider field of view andsimplifies aiming the telescope at the desired object. The maximummagnification should be used only for particularly clear objects such as themoon, which is relatively close to the Earth and very bright, permitting goodresolution of details at high magnification. ERECTING EYEPIECE The 1.5XErecting Eyepiece not only increases the magnification of telescope but alsocorrect the direction of the image. For example, a telescope, which has amagnification of 60X, will have a magnification of 90X when a 1.5X ErectingEyepiece is used. Moreover, when the telescope is used to view landscope, theerecting eyepiece can straighten out the image.
