Mirror Grinding Machine
2015-8-14 If you don't have a gear box, you should stick with the M-o-M power head design. In the configuration shown, the reducer shaft output is 50 rpm, the eccentric rpm is 11, and the turntable rpm is 67. This is typical for grinding and polishing. For figuring, I have another set of pulleys that spin the eccentric at 25 rpm and the turntable at 11

George Willis Ritchey: Astrophotographer Mount
2019-3-14 Ritchey wore many hats. He was an astronomer, a telescope designer, and an expert optician. He took the technology of mirror grinding to new levels of perfection —such that his 60-inch mirror grinding machine now rests in the Smithsonian. He is the “R” in the RC optics used in most large telescopes today, such as the Hubble Space Telescope.

Building a fixed post mirror grinding machine
2019-8-19 I made the overarm from 1.25" steel tube, cut and fitted to size. Butt-welded, cleaned up with a grinder, painted and trial fit. It seems too low, but I will build sandwiched ply layers, glued together and put everything up on that. You do not have the required permissions to view the files attached to this post.

Mirror grinding Telescope making
2007-2-13 The test is very simple. Rinse and wipe the mirror dry. Draw a grid on the mirror surface with a permanent marker (<--picture) Add the usual half teaspoon of grit, sprinkle with water and grind for a couple of minutes, rotating tool and mirror often. Rinse the mirror and inspect the grid lines.

RCOS :: Telescopes Overview RC Optical Systems
2015-10-24 The Ritchey-Chrétien optical design is a specialized Cassegrain telescope designed to eliminate coma, thus providing a relatively large field of view as compared to a more conventional configuration. An RC has a hyperbolic primary and a hyperbolic secondary mirror. Since Ritchey-Chrétien optics are two mirror optical systems, they have no

Best 4 Ritchey-Chretien Telescopes On The Market In 2022
2022-4-9 In my opinion, the best Ritchey-Chretien telescope on the market is Orion 08266 Ritchey-Chretien 10 inch f/8 Optical Tube. Thanks to its hyperbolic mirrors it ensures a wide flat virtually coma-free image of the object you are observing. It also has three cooling fans an internal light baffles that are specially designed to keep any stray light

Making a homemade mirror grinding machine Cloudy
2006-3-6 Gordon will know more about the math for different mirrors and different sizes. I recall for mine it was about a 70% tool diameter. The bucket Gordon used to make the tile tool was 8 15/16", 70% of 12.5" ends up at 8 3/4". Looking back at my notes I used the tile tool primarily at the 70% zone of the mirror.

2017-12-21 STAR INSTRUMENTS guarantees a minimum of 1/4 wave front, 1/20 wave r.m.s. on all systems. STAR INSTRUMENTS continues to be concerned with the false advertising claims being made by amateur optical suppliers who claim 1/10 to 1/20 wave optics. These claims tend to confuse the amateur astronomer into believing you must have 1/10 wave optics, when

A New Ritchey-Chrétien Telescope for Astrophotography
2018-4-28 The iOptron Photron RC6 is a Ritchey-Chrétien telescope, the first of its kind to ever grace my backyard. By design, an “RC” telescope uses hyperbolic primary and secondary mirrors. Compared to a traditional Newtonian reflector design, this RC6 is said to offer a coma and chromatic aberration free results. Quite an impressive feat for a

Design of Reflective Three Mirror Anastigmat Telescope
2022-5-6 The two mirror Ritchey-Chrétien telescope using rotationally symmetric hyperbolic surfaces was designed and built. The optomechanical design incorporated an external tube to align the primary and secondary mirrors in the axial, radial and tilt directions. The TMA achieves better performance because of the addition of a third mirror.

Some facts about RC versus CDK Astrosysteme
2021-8-2 Ritchey Chretien (RC) The RC was invented by 2 Astronomers (Ritchey and Chretien 1910. It uses a hyperbolic primary mirror and a hyperbolic secondary mirror. Since it is THE 2 mirror design with the smallest off-axis aberrations it is the most common telescope design used in professional telescopes (Hubble Space, VLT etc) Dall Kirkham (DK)
