We will be glad to help. All observing is done with the telescope East of the polar axis; the telescope can no longer be used West of the pier. The bigger the aperture of a telescope, the more light it will gather, allowing the observer to see more detail on celestial objects and ascertain finer details that a telescope of lesser aperture may not see. Most of us won't be able to realize the dream of an observatory, but for those who have the means and the land available, it is a wonderful way to start observing at a moment's notice and never have to set up your telescope again. You do know that whatever you spend on the telescope, you will probably spend more than that on the observatory to house it.

Professional telescopes come with an array of advanced features for professionals in the field of astronomy, as well as for dedicated amateur astronomers who require optimal equipment for observation and astrophotography. Since the Ritchey-Chretien telescope uses mirrors to gather light it is technically a reflector, but unlike the more common Newtonian, the RC - short for Ritchey-Chretien - has a Cassegrain configuration. The eyepiece nomenclature is expressed in its focal length in millimeters. Longer focal length telescopes have a narrower field of view but more magnification, while a shorter focal length telescope has a wider field of view that works great for big, faint deep sky objects viewed visually or for astrophotography. Any laser collimator should work, but we recommend getting one that matches the size of your focuser, which is 2" in most cases. Get a Dobsonian telescope if you want a lot of aperture for less money and don't care about motors and electronics! No cheapo wood construction for these behemoths! Then spare cash for a yacht or plane. An eyepiece is a group of lenses housed in a small package that is closest to the eye when used with a telescope, microscope, or spotting scope.

The NexStar 8SE is a portable Schmidt-Cassegrain computerized telescope that is easy to use and has 8 inches of aperture to see deep into space. 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. Telescopes on computerized Alt-Azimuth mounts, like those included with the Celestron NexStar SE line of telescopes, do a great job for both day time and night time observing, however it would not be considered the "best" mount if you plan to do astrophotography. The smaller the f number, the wider the field and more optimized for astrophotography. The biggest telescopes in the world are often the most . We recommend a computerized equatorial mount to make it easier to align, find and track celestial objects.

It is specially designed to ensure a smooth and accurate performance of the telescope. "text": "Yes, as with all reflector designs, RCs do need to be collimated and usually somewhat frequently. Each bay comes with a table top / shelf. "text": "RC telescopes use hyperbolic mirrors to eliminate optical errors like coma and chromatic aberrations off-axis while producing the flattest focal plane possible without lenses." In addition, they are very well corrected optically, meaning you don't need additional accessories. The H142-One receiver can be installed on a 19 rack but it can also be placed on a table close to the control computer. 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.

Reflector telescopes are commonly called Newtonian Reflectors, or simply a Newtonian in deference to their inventor, Sir Isaac Newton. Thats because reflecting telescopes use mirrors, which provide more sensitivity to all wavelengths of light and dont cause chromatic aberrations like color fringing. In fact, the EdgeHD focal plane is 3 times flatter than a standard SCT! While you can buy a manual equatorial mount and add dual-axis motors and a hand controller for astrophotography, these days most people prefer the computerized equatorial mount, like the Celestron Advanced VX Mount.
