Telescopes with larger optical diameters collect more light, which leads to an increase in brightness and image resolution compared to smaller instruments. The 6" f/4 Newtonian Astrograph Reflector features a precise, 2" dual-speed (10:1) linear-bearing Crayford focuser which lies 7" back from the front of the 22.5" long optical tube. }, { Standard Newtonians suffer from coma around the … Versatile 6" reflector telescope and sturdy equatorial (EQ) mount and tripod excels at all-around night-sky performance. The reflector's 6" aperture and fast focal ratio will amaze you with high-contrast views of the cosmos. Intermediate Level - These scopes offer higher performance and more advanced features than Level 1: Beginner models. An included 2" diameter extension tube adds 1.38" (35mm) of length to the focuser for visual use. In metric units, this is: Resolving power (in arc seconds) = 116 divided by aperture of telescope (in millimeters). defaultImage: '', Newtonian reflectors will have either a spherical shaped mirror, which is less expensive to produce, or a higher quality parabola, which does not result in spherical aberration. Fast 6" f/4 Newtonian optics for wide-field imaging with DSLRs and a wide range of CCD and CMOS astronomy cameras Fully and rigorously tested on site for cosmetics, mechanical operation, and optical performance by a master optician to ensure excellent overall telescope operation and customer satisfaction (an Agena exclusive service) width: 90, defaultImage: '', entityId: 100119, entityId: 99631, Now an employee-owned company, we pride ourselves on an unswerving commitment to best quality products, value and unmatched customer care. field, Extended length front tube to block ambient light, © Copyright 2020 Camera Concepts & Telescope Solutions to hear about our new products height: 160, defaultImage: '', defaultImage: '', This warranty gives you specific legal rights.

These scopes will appeal to the more technically inclined. Make sure this fits by entering your model number. entityId: 99809, width: 160, height: 160, This recessed focuser position helps maximize contrast by blocking stray off-axis light for high-resolution performance. }, { defaultImage: '', The Baader MPCC MkIII virtually eliminates coma in fast Newtonian reflector telescopes. Both primary and secondary mirrors boast enhanced reflectivity (94%) aluminum coatings to optimize contrast with a protective silicon dioxide (quartz) overcoat. }, { defaultImage: '', We offer binoculars for every viewing interest, including astronomical binoculars, compact binoculars, waterproof binoculars, birding binoculars, and sport and hunting binoculars. height: 160, and special offers. This effect may not be noticeable at lower powers, but at higher powers the atmosphere will dramatically blur the object, reducing the quality of the image. layers: 'VID017-IntroCollimate' However, it is usually atmospheric seeing conditions (not the telescope) which limits the actual resolving power on a given night; rarely is resolution less than one arc-second possible from even the best viewing locations on Earth. 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. This is important to keep in mind when observing astronomical objects which require high resolution for best viewing, such as planets and double stars. Our 8" aperture deep-sky imaging specialist has features usually reserved for much pricier astrophotography telescopes. Because we sell direct, we can offer you tremendous value at a great price. 2" extension tube for visual use Versatile 6" reflector telescope and sturdy equatorial (EQ) mount and tripod excels at all-around night-sky performance. entityId: 102119, }, { defaultImage: '', 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. Orion Optics VX8 f/4.5 Newtonian reflector Orion Optics’ VX series is aimed at those who want a quality, easy to use telescope. With very fast f/4 optics and 94% reflectivity coatings, the Orion 6″ Newtonian Astrograph will help you acquire outstanding high-resolution images of deep-sky objects with delightfully short exposure times so you can get great results in less time. Orion's Telescope Buyer's Guide is a great place to start. Order received after noon will ship the next business day. 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. layers: 'Artimg-Choose_Scope_Astronomy_square' defaultImage: '', entityId: 99813, Please send me email about sales, new products, and astronomy. The distance from the center of a curved mirror or lens at which parallel light rays converge to a single point. }, { }, { width: 160, width: 90, For telescopes, the optical diameter (also known as aperture) is the size of a telescope's main light-collecting lens or primary mirror, measured in millimeters or inches. This telescope was designed with the goal of being ideal for the astronomer looking to capture high-resolution images of deep-sky objects with minimal exposure time, letting you maximize every hour of precious night-time that you can get with your scope set up and … Orion 6" f/4 Newtonian Astrograph Reflector Telescope. The Superwide 2" Prime Focus Adapter provides the widest possible clear aperture to minimize vignetting - darkening around the edges of the image sensor - in DSLR astrophoto exposures, even when using cameras with large, full frame sensors. }, {
