But after approximately 300x, theory breaks down and real world problems take over. Orion 6" f/4 Newtonian Astrograph Reflector Telescope - 10269 . }, { In metric units, this is: Resolving power (in arc seconds) = 116 divided by aperture of telescope (in millimeters). Designed for astrophotography with telescope focal ratios ranging from f/3.5 to f/6, this Coma Corrector delivers tack-sharp stars across a 35mm frame size. defaultImage: '', }, { For consistent results every night, an Orion-exclusive steel reinforcing plate underneath the focuser eliminates flexure, even with heavy cameras and other imaging gear attached. Narrow Vixen-style dovetail mounting bar Standard mirrors are made from material such as Soda-Lime Plate glass and BK-7 glass. "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. }, { }, { Not sure how to choose a telescope? defaultImage: '', sourceSelector:'' width: 90, From our entry level beginner telescopes for amateur astronomers to our Dobsonian telescopes to our most advanced Cassegrain telescopes and accessories, you can find the best telescope for you. entityType: 'product' width: 160, entityId: 99861, }, { entityType: 'product' }, { An oversized, 63mm minor axis secondary mirror provides excellent field illumination for DSLR and CCD cameras. }, { layers: '24781' Versatile 6" reflector telescope and sturdy equatorial (EQ) mount and tripod excels at all-around night-sky performance. The rolled-steel Newtonian Reflector optical tube's 6"-aperture parabolic primary mirror measures 610mm in focal length, making the optically fast f/4 Astrograph a perfect choice for going after wide-field images of distant deep-space objects. These scopes will appeal to the more technically inclined. A 6-inch Dobsonian reflector telescope is just too big and awkward for some people. field, Extended length front tube to block ambient light. What's more, this compact imaging specialist is conveniently lightweight at just 12.7 lbs., so it doesn't require a huge mount to support it. Telescopes with larger optical diameters collect more light, which leads to an increase in brightness and image resolution compared to smaller instruments. entityId: 102125, }, { Beginner Level - Suited for a wide range of uses, these telescopes are simple to operate and set up. height: 160, Both primary and secondary mirrors boast enhanced reflectivity (94%) aluminum coatings to optimize contrast with a protective silicon dioxide (quartz) overcoat. defaultImage: '', }, { Lowest useful magnification is the power at which the exit pupil becomes 7mm in diameter. layers: 'VID183' }, { entityId: 101450, width: 160, Very good optical and mechanical quality. height: 90, Orion 6" f/4 Newtonian Astrograph Reflector Telescope OTA entityType: 'product' }, { entityType: 'product' Contrast-enhancing extended tube length. The limiting stellar magnitude is a measure of the faintest star you can see through the telescope. Of course, the 6" f/4 Newtonian Astrograph can also be used for spectacular visual observations of deep-sky and solar system based celestial objects. This warranty is for the benefit of the original retail purchaser only. It is well-built with nice fit and finish for the price and should last a lifetime. entityId: 99816, }, { entityType: 'product' height: 160, entityId: 99897, }, { But anyone with the slightest technical bent will have no problem getting familiar with these models.
