How to maintain the telescope, how to adjust the telescope, how to adjust the telescope

The Galaxy Telescope has the answer for you:

When we buy our favorite telescope home, while using it to enjoy the beautiful scenery, we should also pay attention to maintenance and maintenance, the following are some maintenance tips:

1.Ensure that the optical components such as the telescope are stored in a ventilated, dry and clean place, and if possible, the desiccant can be placed in the lens barrel and replaced frequently;

For small optical components such as eyepieces, they can be placed in a drying oven or drying tank. Do not use binoculars in rainy and snowy days, windy sand, and humidity (more than 85%).

2.If there is dust and other dirt on the optical mirror, it should be gently blown off with an ear wash ball, and never wiped with a cloth and a stiff brush; If you want to clean the mirror, you should use absorbent cotton to occupy a mixture of alcohol and ether 50% each, wipe from the center of the mirror surface in one direction (not in reverse) to the edge of the mirror, and constantly replace the absorbent cotton ball until it is clean.

3.The mechanical and tracking system of the telescope is a high-precision transmission system, which generally does not need frequent maintenance, but should be regularly added with the same type of lubricating oil (grease) according to the requirements of the manual; If the model is different, please clean the original lubricating oil (grease) with kerosene, etc., and then add new lubricating oil (grease), be careful not to mix different types of lubricating oil (grease).

4.The control system of the telescope should be checked from time to time, and the operation should be strictly in accordance with the requirements of the manual, and the water vapor and foreign matter should be prevented from entering the circuit part at ordinary times, and the battery should be taken out and stored if it is not used for a long time.

5.The reflective surface of the reflecting telescope should be coated regularly (generally 3 years, if it is well maintained, it can be five years or more if the environment is good) to ensure that the reflector surface has good reflectivity.

6.In addition to the usual protection, the surface of the telescope should be cleaned from time to time, and attention should be paid not to use organic solvents. A complete astronomical telescope is a sophisticated optical instrument composed of optoelectromechanical and electrical equipment, subject to the rules of use:

enhanced maintenance; For equatorial devices, the polar axis should be adjusted to the latitude of the observation site and within the meridian; The focus of the astronomical telescope is very important, pay attention to the difference between people and methods; The microclimate caused by the observed environment cannot be ignored; The telescope should always be in equilibrium in all directions.

You can go to the Galaxy Telescope Knowledge Zone to have a look, and you can directly search for "Galaxy Telescope", where there is a lot of relevant knowledge about the purchase, maintenance and use of telescopes.

You have to choose the better one.

1. The positive and negative diopters of the left and right eyepieces of the telescope.

The scale is adjusted to 0 scale. Hold the left and right sides of the telescope with both hands, search for distant targets and stretch or press the left and right lenses at the same time, so that the eye distance of the telescope is the same as that of the human eye.

When the adjustment is the same, the adjustment is stopped.

2. After searching for the target and locking the target, rotate the left eyepiece vision handwheel to make the target image and reticle image of the left branch system of the telescope completely clear, and then rotate the right eyepiece vision handwheel to make the target image of the right branch system completely clear, and then complete the adjustment of the observed target. Because the telescope optical path is designed with a dynamic autofocus function, there is no need to refocus when observing a target at a different distance when the telescope clarity is adjusted.

3. When the ambient light is dim or when observing at night, it is recommended to use a telescope with an exit pupil diameter of more than 7mm. Because the diameter of the pupil of the human eye is about 2-3 mm during the day and 6-7 mm in the dark, the telescope can collect more light than the flesh-key eye.

Summary. Pro, 1Open the tripod and open it flat on the ground, with the foot marked with n facing north, and if you don't know the direction, you can use a compass.

Take out the equatorial mount, fix the right ascension and declination locks, install them on the tripod, hold the screw up and tighten it slightly. 4.Tighten the attachment disc screws so that they hold firmly against each leg of the tripod.

Pro, 1Open the tripod, open it flat on the ground, with the foot marked by n facing north, and if you don't know the direction, you can use the local lead finger to contain the old bridge south needle. 2.

Take out the accessory disk, unscrew the button at the bottom of the tripod, attach the accessory disk, and screw the button. (The name of the part can refer to the standard drawing of the product) 3Take out the equatorial mount, fix the right ascension and declination locks, install them on the tripod, hold the screw up and tighten it slightly.

4.Tighten the attachment disc screws so that they hold firmly against each leg of the tripod.

5.Take out the hammer rod and accessories, install it on the equatorial mount, unscrew the bottom screw of the hammer rod, install the hammer, and tighten the bottom screw. 6.

Attach the trimmer screws of right ascension and declination and tighten the screws. 7.Unscrew the two screws at the top of the equatorial mount, put the dovetail plate at the bottom of the telescope barrel into the card slot, tighten the screws, pay attention to tighten the large screws first, and then the small screws (when dismantling, the small screws are small first and then large).

8.Unscrew the screws at the top of the mirror and tube, install the finderscope and base into the card slot, and tighten the screws. 9.

Open the lid at the end of the lens barrel, attach the zenith lens and eyepiece, and tighten the screws.

The use of telescopes: first of all, adjust the distance between the two lens tubes, until the two viewing angles are a circle, so that the distance seen by the two lens tubes is exactly the same as human vision. Then use the mechanism handwheel to adjust the sphere of influence of the left eye, and then use the vision handwheel of the right mirror to adjust the range of vision of the right eye.

Finally, aim the telescope at the object that needs to be seen, and only need to adjust the mechanism to see the object of observation.

The range of telescopes that we generally use is limited, and we can follow the above operation methods to make things see more clearly, but there are some telescopes that cannot be operated in this limb, because its precision is very high, and if you adjust it a little, it may be far worse. Astronomical telescopes can not only magnify distant objects, but also help people see the parts of the spectrum beyond visible light, including gamma rays, X-rays, ultraviolet rays, infrared rays, microwaves and radio waves, which are relatively effective.
