It was during this review that he discovered the planet Uranus. The Vixen R130Sf Newtonian Reflector Telescope came with two eyepieces a 20mm and 6.3mm and this weird looking extension I wasn’t familiar with.
He used his own 7-foot telescope (which would have been very similar to this one) with a 6.2 inch aperture magnifying images 227 times (depending on the eyepiece used), to make his 'second review of the heavens' in 1781 from his house in New Kings Street, Bath. SCT designs are not considered reflectors, but are a hybrid of reflector and refractor. Dobsonian is a type of mount that houses a Newtonian reflector. Thanks to that feature you can be sure that this telescope will provide you with the most beautiful view of the objects you are observing. All reflector (Newtonian) telescopes will have the secondary mirror in the middle. William Herschel made and sold many telescopes of this type. This Newtonian reflector telescope features fully coated glass optics that are specially designed to protect your eyes and provide a much higher light transmission. Despite being one of the simplest optical designs, the Newtonian performs very well and is easy to manufacture. Carson Red Planet Newtonian Reflector telescope is a precision instrument provides powerful, razor sharp views of our universe due to a reflecting mirror. An objective mirror speculum (a type of metal) measures 6.3 inches. The Newtonian was the first reflecting telescope. There are two types of refracting telescopes depending on the combination of lenses. A finder telescope is incomplete and attached to the side of tube above the eyepiece by a broken mounting. A telescope that uses only the refraction of a lens is called a refracting telescope. A secondary mirror is in place with a cover and three adjusting screws held on a stem connected to a brass eye piece mount, itself with adjusting (focusing) screw and brass cover. There is a round front cover held by three springs. Four motions: fine vertical and fine horizontal, two coarse vertical motions, one raising the front support, the other raising the tube behind, the tube resting in a rectangular frame running in grooves in the stand and the frame connected by a gut line to a handle. This is a 7-foot Newtonian (reflector) telescope.
