Redesigning of a Classic Model- The Truss Tube Telescope
April 11, 2008
The First Ever:
Ever since Galileo created the first telescope way back in the year 1609 there has been no looking back in this field of astronomy. The world has changed ever since then and the mysteries of heaven have continued to excite the enthusiastic astronomers to learn more and more about the space and the vast solar system. Galileo saw the wonderful celestial bodies which are a part of our solar system, we should thank him because he was the first person on this earth of see the craters on the moon.
There has been no looking back since then thousands of astronomers both professional as well as the amateurs have spent lots and lots of their times towards watching the celestial bodies. For centuries the popular style of telescopes were that used the refractor type of lens which collected the light of the electromagnetic spectrum or the Newtonian style which a reflector telescope which uses a collection of mirrors to see into the depths of the outer space. The truss tube telescope changed the whole concept of viewing the celestial bodies after its advent into the field of astronomy.
One Mr.Mark.U.Serrurier designed this truss tube telescope in the year 1935. This telescope is sometimes referred as a Serrurier truss telescope. Mr. Surrurier was an engineer who was working on the 5 meter Hale telescope at Mt. Palomar, he used a different method to assemble the telescope tube and this was the new type of Newtonian telescope.
Eliminations
The truss tube telescope eliminates flexing by supporting the primary and secondary mirrors with two sets of opposing trusses right before and after the declination pivot. Truss tube telescopes design allows for an equal amount of flexing. This lets the optics to remain on a common axis.
When the truss tube telescope is flexing the two sets of trusses are doing equal amounts of work. The “top” trusses will be resisting tension while the “bottom” trusses are resisting compression. The result being that the optic elements will stay parallel with one another and the optics and the truss tube telescope will stay in collimation no matter which way the telescope is orientated.
The main feature of this truss tube frame is that it is light in weight and can easily collapse and this allows amateur astrologers who can afford to buy this telescope because it is reasonably priced and this can easily be fitted into the car and can be assembled without wasting much of their time while they are attending “star parties” or even they have gone out somewhere to gaze at the stars. The best part of this truss tube telescope is that all most all the parts can be dismantled or broken down into smaller parts which means more people can have the specifications of a scientific telescope with convenient ease.
Many Brands Have Come Up
Many a brands and models of truss tube telescopes have come up in the market, but the Dobsonian design was the original of the many truss tube telescope which they have brought out into the market. To-day with the advent of the latest technology that has been available people or say for that matter astronomers be it the amateurs as well as the professional are utilizing this benefit for furthering their interest in this field of science and thus this field of science has gained a lot of popularity.
Summary:
The truss tube telescope has gained a lot of popularity because it has all the latest technology that is available today and as it is reasonably priced it can be afforded by all and the best part of this telescope is that almost all the parts can be dismantled so this helps a lot because it does not occupy much of a space and can be reassembled easily.
Got something to say?
