Refractor telescopes refract, or "bend" incoming light to a focus by means of an objective lens. template left */ At home, it uses removable wheels to get it outside and back from your garage or storage shed (we hope you have at least a two-car garage! Telescopes with larger optical diameters collect more light, which leads to an increase in brightness and image resolution compared to smaller instruments. The second member of our Monster Dob family is a 40" giant that offers almost 25% more light than it?s little 36" brother or four times the light gathering power of a 20" telescope. And consider adding our email address (news@oriontelescopenews.com) to your email safe senders list, address book or contact list. These monsters are the kind of size that are being used in Universities and Observatories and now they are available for home and amateur use. swag . /* 160x600, created 1/10/10. Cassegrain telescopes, such as Maksutov-Cassegrains, "fold" incoming light using two mirrors and a front "corrector" lens. Standard achromatic refractors routinely use Crown and Flint for the two elements, but more expensive apochromatic refractors can use ED (extra low dispersion) glass for one or more of the lenses. 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. The "theoretical" limit generally is 50x the aperture of the scope in inches (2x the aperture in mm). and special offers. Finding objects is a breeze, 27-point flotation mirror cell and eight-point wiffle-tree edge support system prevents mirror deformation and keeps images crisp. Moonlite, Argo-Navis, and ServoCAT are trademarks of their respective companies. The distance from the center of a curved mirror or lens at which parallel light rays converge to a single point. google_ad_height = 600; Refractors use glass lenses to focus the light, and the glass material plays an important role in the quality of the resulting image. Secondary mirror features spring loaded collimation adjustments $2,899.99. You can find astrophotography "how to" tips and share your best astronomy pictures here. Referring to the manual is highly recommended. The specs of even the smallest of these new Orion Monster Dobsonian telescopes are filled with superlatives. Many years ago, you bought your first telescope ? 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. Orion Dynamo Pro 12V Rechargable Power Station Collapsible secondary cage light shield Advanced Level - These scopes provide the best performance but may require more skill to master and appreciate. 5 cooling accelerator fans located in mirror box A motor drive automatically moves the telescope in right ascension at the same rate as the east-west drift of the stars so stars can be continuously tracked in the eyepiece without manual adjustment. 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. Orion offers telescopes for every level: Beginner, Intermediate, and Advanced. 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. The Orion 40" Monster Dobsonian can shed a lot of light on that little problem. Exclusive preview for our Facebook fans – No. They are Truss-tube dobsonians and the line has three sizes of telescope: A 36 inch, a 40 inch and a 50 inch! Browse through our online Image Gallery to see amazing astrophotos taken by Orion customers and staff members using Orion astrophotography equipment. home. Now, your latest "big" reflector reveals details and structure in many NGC objects. Telescopes on either very lightweight mounts or non tracking mounts (such as Dobsonians) are capable of only very short exposures such as lunar photographs. Thanks to its 16" aperture parabolic primary mirror, the Orion SkyQuest XX16g GoTo Truss Tube Dobsonian will astound you with spectacular views of the night sky. For visual astronomers, it is the ultimate observing experience. Binoculars with larger objective lenses collect more light, which increases image resolution and brightness. telescope ? 1/8 wave or better, diffraction limited, star-tested optics, razor sharp and hand figured in North America by Master Optician Normand Fullum. Premium quality f/4 optical system gives a whopping 144" (3658mm) focal length to deliver exceptionally sharp, bright images with generous image scale, Enhanced (96%) coatings on the primary and secondary maximize light throughput, Low-expansion borosilicate glass molded in a honeycomb mirror blank design make it exceptionally strong, yet light, and assures good optical performance, even as the temperature drops, Transportable! pictures. 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. The premium optics and light-gathering of telescopes found in observatories and universities are now brought to your home by Orion. Argo-Navis(TM)* electronic setting circles with over 29,000 astronomical objects in the on-board database This Monster Dob takes up an entire parking space when assembled). Short focal ratios (f/5, f/4.5) produce wide fields of view and small image scales, while long focal lengths produce narrower fields of views and larger image scales. You're already on our email list, scopes. The Monstrous 36" aperture parabolic primary mirror (914mm) collects over 1000 square inches of light - four times the light of "ordinary" 18-inch telescopes! Great for families, young people, and folks who don't want to mess with equipment but just want to take a look. But anyone with the slightest technical bent will have no problem getting familiar with these models. You enjoyed new vistas: real detail on Mars and Jupiter.
