Refractors use glass lenses to focus the light, and the glass material plays an important role in the quality of the resulting image. The mirror collects 78% more light than a 6" mirror, so you get a significant increase in ability to observe dust lanes in nebulas, resolve the cores of prominent globular star clusters, and to reveal some of the more subtle structures in faint galaxies. Lowest useful magnification is the power at which the exit pupil becomes 7mm in diameter. entityType: 'product' defaultImage: '', height: 90, layers: '15174' }, { "Diffraction Limited" means that the limits of image detail are determined by the physical properties of light, and not by optical defects in the telescope. }, { }, { Enhanced-reflectivity mirror coatings boost the XT8 Classic Dobsonian's mirror to 94% reflectivity so as much light as possible is transmitted to the eyepiece, for clear and bright views. Standard mirrors are made from material such as Soda-Lime Plate glass and BK-7 glass. }, { Please send me email about sales, new products, and astronomy. Front brace
Glass with Pyrex or other low thermal expansion material will not change shape as dramatically during the cool-down period, resulting in more stable images during this period. Powers below this can still be reached with the telescope to give wider fields of view, but the image no longer becomes brighter at a lower power. Any of these scopes will show you countless lunar craters, Saturn's rings and a myriad of star clusters and nebulas! For complete warranty details contact us at 800-447-1001.
