Astronomy Tutorial

With the tutorial application of astronomy you will get the best explanations of astronomy experts on what should be your first telescope, which are the

Main celestial bodies that you can see in the film, care and cleaning of your equipment, which are the best moments for a better observation, election

Of eyepieces, etc.

Trambien will explain the different telescopes that are on the market, and for each one indicated, we differ in three:

- REFRACTORS: This type of telescope has a long, relatively thin tube with the main lens (lens) on the front, which collects and focuses light.

The simplest type of astronomical telescope has two lenses. Both are convex; That is, thicker at the center than at the ends. The nearest lens

 The object is called objective. The light from a distant source passes through this lens and reaches a focus as a "real" image and inverted inside the tube of the telescope

 . The lens of the eyepiece increases the image formed by the lens.

In an astronomical telescope, the "virtual" image formed by the eyepiece is inverted.

- REFLECTORS: Uses a large and heavy concave mirror, instead of lenses, to collect and focus the light. You look through the eyepiece on the side of the

Tube, near the upper end.

Light from distant objects like stars enters the tube of the telescope in parallel rays, which are reflected in the concave mirror towards a flat mirror

diagonal. The diagonal mirror reflects light through an aperture on one side of the telescope tube to an eyepiece lens.

Reflecting telescopes may be larger than refractors because the curved mirror can be supported over its entire surface, while a large lens only

Can be supported at its ends.

Larger mirrors have advantages because they can collect more light. Among the modern reflecting telescopes is the 508 cm reflector of the

Monte Palomar Observatory in California (USA) and the 400-cm Observatory at Cerro Tololo near La Serena, Chile.

- CATADIOPTRICOS: Also called complex telescopes.

They use lenses and mirrors. The objective is a concave mirror but in the aperture there is a correction lens that also holds a secondary mirror.

The tube is wide and short, the eyepiece is located at the posterior end of the lens.

The retro-reflectors are generally powerful and high-quality instruments that, thanks to a more complex design, are compact in size and therefore easier

To transport and to handle.

You will find all this explained in a didactic way in comfortable video tutorials.
