The mount you choose also dictates the total weight and heft of the telescope system. The observatory contains two historically important telescopes: the 100-inch (2.5 m) Hooker telescope, which was the largest aperture telescope in the world from its completion in 1917 to 1949, and the 60 . For the same price as a refractor, you can get a much larger aperture reflector. Folks who want to look at the Moon, Saturn and Jupiter occasionally but who are not interested in photography would do perfectly well with a medium-sized refractor on a simple quality alt-azimuth mount, whereas those who want to do photography would require an equatorial mount with either computerization or dual axis motor drive. Is it a rapid pointing telescope or a 'sit and stare' telescope? Click the Learn More Button to read more! Start Chat A Cassegrain also uses mirrors to gather the light, but has a folded optical path like a catadioptric telescope. RCs arenot ideal for wide field deep sky work. The point is, if you want aperture, portability AND electronics, look into a Schmidt-Cassegrain or EdgeHD telescope in the size you'd like, and then choose whether to have it ride on an equatorial mount and tripod or a computerized alt-azimuth mount and tripod. Yes, as with all reflector designs, RCs do need to be collimated and usuallysomewhatfrequently. A Schmidt-Cassegrain, which belongs more broadly to the Catadioptric telescope type, uses a folded optical design incorporating both mirrors and lenses to gather and bring the light to focus. The feedhorn is designed to allow the reception of dual polarization with support for two professional Low Noise Amplifiers (LNA) for the 1420 MHz frequency. This takes us back to the solid equatorial mount, which is required for long exposures of galaxies, nebulae and other deep sky objects. Few of us will be able to buy one of these 1 or 2 meter scopes (I asked my HOA and they said they won't allow it), but it is important to understand that substantially the same software, hardware and technology that goes into these professional telescopes is also used on their smaller models like my little CDK20 telescope and L-500 mount. What is the science objective? If you're looking for the hardware required to perform research level astronomy, look no further- the pieces in this category are the very finest available.

Telescope Cases, Covers & Dobsonian Shrouds, Apertura 6" f/9 Ritchey-Chretien OTA telescope, telescope smartphone adapter to take quick photos, Refractors require the lowest maintenance of any telescope design, The closed tube design of a refractor keeps out air currents that decrease image quality, By adding an image-erect prism diagonal, a refractor can be made to display images that are oriented correctly for daytime use, Longer focal length refractors achieve higher contrast images and darker background skies, Refractors have a higher cost per inch of aperture than reflectors, Refractors are expensive to make in apertures larger than 6", making them prohibitive for most people. In general, the activities that many schools develop in astronomy are usually made with optical telescopes because instruments for other electromagnetic spectrum bands are considered too expensive or difficult to use. Achromatic refractors suffer from chromatic aberration, which can be seen as purple glow around bright objects. Itallows you to control the antenna position and acquisition parameters of the receiver. This is because your exposure time would be quick enough that the Earth's rotation would not come into play. H142-One receiver has been specially developed together with Bologna INAF Institute of Radio Astronomy specifically for SPIDER radio telescopes. Maksutov-Cassegrain are great for visual use or planetary imaging, the views will be full of contrast with a darker background sky due to their long focal lengths. The folded light path allows for a short tube assembly even with relatively large apertures of 8" or more. These become very expensive to produce at large sizes due to the degree of accuracy required to manufacture the mirror. Special/Custom Order - Shipping fee will be billed separately at the time of shipping. There is plenty of things a smaller scope can do! A shorter tube length makes the SCT far more portable than a classic Newtonian or refractor of the same aperture. SPIDER 230C radio telescope is not provided with an equatorial mount (we suggest the use of a EQ8 SynScan mount, you can read how to use it in the SPIDER 230C user manual) that must be added in order to make it work.
