Each bay comes with a table top / shelf. Consumer-grade telescopes can have imaging defects such as color fringing a kind of chromatic aberration that happens when the lens is unable to bring all wavelengths of color to the same focal plane. The focal length is the distance, usually measured in millimeters, between the primary mirror or lens and the point at which the image comes to focus. The focal length also affects the field of view.

The reason for this is because RCs usually have a large central obstruction, which is how much light is obstructed entering the front of the telescope due to the size of the secondary mirror. "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." Faulkes Telescope North (FTN) is located at Haleakala Observatory, on Maui, Hawaii, and Faulkes Telescope South (FTS) is at Siding Spring Observatory (SSO), in eastern . To figure out the magnification, simply divide the focal length of the eyepiece into the focal length of the telescope. If the telescope is for an adult, how much weight could they comfortably lift? The UH 2.2-meter telescope (center) was the first large telescope on Mauna Kea. It is specially designed to ensure a smooth and accurate performance of the telescope. You can buy both reflectors and refractors in shorter or longer focal lengths. Copyright var date = new Date(); document.write(date.getFullYear()); NexDome Observatories Store. "text": "On the high end, RCs are more expensive because they use a hyperbolic primary mirror design. While the telescope accessories you need depend on the telescope and the kind of observing or photography you plan to do, all telescopes could benefit from a Moon Filter! Here is where the second and third parts of the adage come into play: "that you can set up by yourself and will use." Achromatic refractors suffer from chromatic aberration, which can be seen as purple glow around bright objects. We recommend the Apertura AD 8" Dobsonian for its quality and included accessories. To get the most out of the information from this point on, take a look at the five questions we asked in the How to Choose a Telescope section and think about how they apply to you. With a diffraction-limited 100mm image circle, the PW1000 is designed to excel at imaging on the largest format CCD cameras available today. You'll look at that big beautiful telescope and say, "maybe tomorrow night". I have a nice spreadsheet I can send you that takes your detector parameters, star FWHM, aperture, and calculates the signal to noise ratio of a star image for a given exposure time. I say "current" because the sky's atmosphere is always changing and will be different not only from night to night, but sometimes from hour to hour!
