Gregorian, exist but are less common. Reflecting telescopes use mirrors at the back of the tube to reflect the light instead of refracting it through a lens. Planet details in 16" f/4. The Dobsonian is a simple, low-cost telescope design made popular in the 1970s by amateur astronomer John Dobson of San Francisco. The Dobsonian (or “Dob”) is simply a Newtonian telescope mounted on a modified alt-azimuth mouth, making it relatively easy to use. Quality and brightness of visual images, and accurate tracking are my Feb 29, 2020 · Above: Optical layout of a typical Maksutov-Cassegrain Maksutov-Cassegrain telescopes are an alternative design to the similar Schmidt-Cassegrain telescope (SCT). Look for a portable telescope, most likely in the 3" to 6" aperture range. How to use Dobsonian Telescopes? Visual Observing. Amateur astronomers prefer Dobsonian telescopes for their large aperture, low cost, and portability. For visual observers, microfocusers are a big improvement over stock focusers. 25 inch celestron Schmidt-Cassegrain computerized Trying to help a neighbor out with getting a telescope. Now I want more light for deep sky observing. 25" Schmidt-Cassegrain and the 10" Newtonian Im looking at are GoTo setups on comparable EQ mounts. A Newtonian telescope is a reflector telescope with a curved primary mirror in the back, a flat diagonal mirror in the front, and a focuser to use an eyepiece or camera in the side of the front. 5 Portability and ease of use; 2. The most popular compound telescopes are the Schmidt-Cassegrain design, a variant of the Cassegrain reflector telescope with a Schmidt corrector plate. Advantages of a Schmidt-Cassegrain Telescope for Astrophotography Classical two-mirror arrangements are Gregorian - the very first reflective telescope design, conceived by James Gregory in 1663 - and Cassegrain (FIG. Welcome to Hubble Optics! Since our establishment in 2003 in Texas, we've delivered to NASA, SpaceX, Apple, the US Army, Princeton University, Stanford University, California State Polytechnic University, and other universities, government agencies, commercial customers, Private Research Institutions, and individual customers around the world. At the opposite end of the spectrum lies the Dobsonian Telescope. Small Newtonian reflectors often have spherical figured mirrors.
