A truss is an assembly of straight columns that create a rigid structure. Our 20-inch telescope is a Truss Tube Telescope. You can also discern the colours of the stars more easily in the Aperture Telescope 20-inch telescope. The colours of double stars such as Albeiro are spectacular. When you look at the Ring Nebula you can see the smoke ring bright and even discern the onion like extensions on two sides of the ring. You can see deeper, many more stars, all sharply focused and separate till the core. Or Messier-13 (M13), the Great Hercules cluster, the real-time view is much better using the 20-inch. It is impossible to photograph the beauty of the intensely dense group of stars in a globular cluster. This is the benefit of using a large telescopeĭeep Sky Objects: When you look at deep sky objects such as globular clusters, the naked eye view is far superior to photographing it. Along with the resolution, since there is good amount of light collected, you can see surface features on planets in high contrast. A 20 inch telescope can resolve much more details on the surface of planets. The resolution of a telescope is a function of its diameter. Planet Observations: The telescope shows great views of the planets, you can see the surface features clearly. You need a ladder to look through the eyepiece when it is pointing at most targets overhead. Views through this giant Dobsonian are always incredible. Dobsonians are the simplest design for a telescope. It can be setup quickly and up and running in just a few minutes.
Dobsonian Telescopes do not suffer from chromatic aberration as in refracting telescopes.ĭobsonian Telescopes are perfect for beginners and amateur astronomers. The optics of a Dobsonian Telescope are of the Newtonian reflecting type. Assembly of the telescope can be completed in 5-10 minutes on site. The telescope is portable, can be separated into three parts, the lower tube assembly, upper tube assembly and the truss tubes.
This is the largest telescope, available on the consumer market in India. With a massive 20-inch aperture you can collect a humongous amount of light from the faint deep sky objects. Even small increase in diameter can be significant increase in brightness and resolution. the square of the radius of the telescope. The light collection increase is directly proportional to area of the primary mirror, i.e. Bye-bye astrophotography, you will be amazed by the views from this telescope.īigger is certainly better, with telescopes.
