Using the above guideline, a maximum magnification of 400x is all that's needed. The Orion SkyQuest XT8 has a minimum magnification of 29x. To calculate the maximum useful magnification, double the opening in millimeters or multiply the opening in inches by 50. The 25-millimeter Sirius Plossl 1.25-inch eyepiece provides a magnification level of 48x with a 52-degree field of vision. In fact, the ability to collect as much light as possible is more important to quality viewing than magnification. With this Orion classic telescope's 1200-millimeter focal length and moderate-to-high magnification, clear nights should provide crisp views. Transmitting as much collected light as possible to the eyepiece provides you with brighter, clearer views of dim, distant objects. The Orion SkyQuest optical tube also contains reflector optics to further improve the transmission of light. In addition, the mirror's enhanced coating increases its reflectivity to 94%, transmitting more collected light to the eyepiece. With its 8-inch parabolic primary mirror, the Orion XT8 5.9 collects a vast amount of light. The sharper the image becomes, the more details you will be able to see. The more light that's collected, the sharper the image becomes. The larger the mirror and aperture opening, the more light that telescopes can collect from the object being viewed. The large aperture of the Orion SkyQuest XT8 5.9 Classic Dobsonian Reflector Telescope provides you with high-quality nighttime viewing.
