From toy models to optical precision

The telescope is an instrument that has always fascinated children and adults, whose origin is very old and whose applications are different, earth observation at the astronomical, or as an aid to navigation, such as sports instrument and even as a weapon of war .

Understanding how to choose a good telescope, therefore, is not as simple as it sounds, especially taking into account the wide range of models offered by the market, and especially from the price difference, which varies from a few tens of euro of toy models for children up 1,000 Euros and beyond of the most high-end models, which include both telescopes by observation both the precision optics for hunters and marksmen.

Which telescope buy, then, given the choice? The answer to this question is simple, just be aware of their needs and the use you intend to make.

The mid-range scopes

The most market economic band, for this particular type of optical instrument, is represented by the toy telescopes; these are suitable especially for those who want to make an original gift, pleasing and at the same time also educational, stimulating the curiosity to know the child. As mentioned above, in this range the prices are very low and the spending range may vary from 10 to 40 Euros or so, depending on the model chosen.

In the middle segment of the market, however, they include a wide range of models for which the price can vary from 200 to 800 Euros, depending on the manufacturer and owned properties.

Most of the copies sold are located in this segment but in fact, for this very reason, we must make distinctions necessary. There are in fact telescopes that are very versatile and can be used both for the observation of the sky for Earth observation; Others, however, tend to be more specific as specifically designed to offer the best in certain fields of application.

As just one example, so if you want a telescope just to go birdwatching, or to use to follow in a close sporting events such as horse racing or football matches, it will be better to turn to a specific model.

If you pose no limits on the type of application, then better to focus on the generic scope that offers the best performance in its category.

The size and weight can influence the choice; if the telescope is very heavy and bulky, in fact, it will be more difficult to carry compared to a compact and lightweight model, and therefore less suitable for outdoor use.

The high-end telescopes

When it comes to telescopes, the mid-range and the high end of the market tend to merge together because there are no substantial differences in instrument types, but only in the quality of manufacturing materials, the lenses and prisms, the focal length that can reach , performance in the eventual offers and accessory equipment.

The same, of course, also applies to the optical target, which represent another type of telescope destined mainly to hunters and marksmen. The models at the top of the range, then, are available at a price ranging from 800-900 euro to rise, depending on the manufacturer, the type of instrument chosen and its features.

Who invented the telescope?

Unfortunately it is not possible to attribute with certainty the exact authorship of the telescope to a specific person; according to historical records, in fact, the first samples of the telescope appeared in the West date back to the early 1600s, in hindsight, however, by further archaeological finds in Mesopotamia, it is clear that already Assyrian and Babylonian had developed rudimentary tools astronomical observation.

In a publication of 1618 becomes the name of a German optician, Johannes Lippershey noted as the inventor of the telescope, but it is also specified that Lippershey had learned the secrets and techniques of construction of this fortuitously instrument, a traveler who was He arrived in his shop.

Subsequently, the physicist, astronomer, philosopher and Italian mathematician Galileo Galilei, was able to obtain one of the telescope specimens made by Lippershey, one coarse tool characterized by a low magnifying power and an equally poor image resolution.

Galileo sensed immediately that further improving the characteristics of the scope of the latter offered considerable potential as a tool to be used in the field of war and military. After managing, using empirical methods, rebuild and also improve the yield of Lippershey telescope, therefore, Galileo quickly produce different specimens with the intent to offer them to the Doge of Venice as instruments of war.

In 1609, in fact, Galileo wrote a letter to Doge where, attributing the authorship of the invention, offered to the Serenissima the telescope for military purposes, demanding in exchange for a chair. The Doge of Venice, fascinated by the instrument, and then attributed to Galileo the chair to life is an annual salary of 1,000 guilders, thereby tying the name of the astronomer Pisa to that of indissolubly telescope.

How does a telescope?

The telescope is an optical instrument used for the close observation of objects that are located at a great distance from the observer, and its principle of operation is based on the refractive properties of the lenses, so it can vary depending on its type. The telescope, in fact, can be of three types: Galilean, Keplerian and prismatic.

The Galilean telescope is constituted by only two lenses, a convergent, plano-convex or biconvex, which acts as a lens and a diverging, plano-concave or biconcave, as a function of eyepiece. The magnification level, therefore, can be varied by changing the focal length between the two lenses, by lengthening or shortening the tube in which they are inserted.

The same principle applies to the Keplerian telescope, but the latter adds a third lens, or even a group of lenses, in an intermediate position between the objective and the eyepiece. Depending on the convexity of the lens, in fact, this can postpone the eyepiece an inverted image; the intermediate lens precisely serves to straighten the real image formed by the lens, and this lens is defined straightening.

The prismatic spotting scope, however, is analogous to that Keplerian with the only difference that for the straightening of the image is not used but a lens precisely a prism, whose configuration can be roof or Porro, from the name of its inventor: Ignatius Porro .

How to build a telescope

Wanting grapple nell’autocostruzione of a telescope, it is advisable to choose the Galilean type since it is the easiest to realize. The material to be found for the construction of a Galilean telescope with a magnification factor of 6 to 6.5x is as follows:

– Two eyeglass lenses of 60 mm diameter, a converging from 0.75 diopters, the focal length of about 133 centimeters, and a diverging from -5 diopters, with focal length of about -20 centimeters, both easily available at an optician’s shop .

– Two cardboard tubes of approximately 5 mm thickness, the first with an inner diameter of at least 60 millimeters and 90 cm long and the second with a smaller outer diameter of 60 mm and length of 60 centimeters. On call without spending as a waste of fabric rolls, rolls of cloth or paper to clean the house.

– A cardboard with a thickness of about 1 millimeter.

Despite the simplicity of design of the Galilean telescope, however, the cutting and assembly of the various components require an accurate work and a lot of patience, as well as the aid of scissors, saw and measuring instruments such as rulers or a gauge, for those who were outfitted as well as a diagram that helps to visualize the different parts to be made and the manner in which to put them together, which is why we refer to a file with specific instructions.

How to adjust a telescope for rifle

A correct adjustment of the telescope is essential for obtaining the utmost precision; before executing it, however, it is important to first verify that the telescope is installed on the weapon so as to be perfectly aligned to the barrel, with a stable coupling and completely devoid of games in the mechanical parts.

For verification, please contact your gunsmith or, if you are in possession of a rifle with a rotating bolt, run yourself pulling the shutter and placing the gun in a stable position of aiming at the target and then, without touching the ‘weapon, alternately sighting the line of sight from the barrel and the telescope to see if they match.

The optical calibration, however should be done via the two adjustment rings placed about halfway down the length of the tube; the operation is obviously performed with the weapon locked on appropriate supports and pointing toward a target located at least 100 meters away.

Acting on nut dell’alzo you will adjust the horizontal axis of the grating, whereas the ring nut of the rule tilt the vertical axis; aiming the target, therefore, necessary to act on both ring nuts until they coincide with its center.

This, however, is only a preliminary calibration which will have to follow a test firing, with the type of projectile usually used. The whole procedure is quite long to explain, given the many technicalities, so we refer to specific documentation on the calibration of the optics.
