[Astronomical Telescope maintenance] How to maintain the astronomical Telescope?maintenance of astronomical Telescope

The purchase of the Telescope is important, but it is as important as maintenance and maintenance.The astronomical Telescope is a precision instrument, which directly affects the use and life of the Telescope. Therefore, it is necessary to use it to use it and be custody. Non -professional should not easily disassemble and repair it.

1. maintenance of optical system

(1) Ensure that the Telescope is placed in a ventilated, dry, and clean place; all eyed mirrors, prisms, secondary imaging mirrors, and other small optical parts attachments should be placed in a dry box or dry tank with desiccant when not in use.At the same time, pay attention to replace new desiccants.Do not use Telescopes, and do not open the object mirror cover in rainy days, wind and sand, and humidity (more than 85%). Especially for reflecting Telescopes of non -sealing windows, gray sand is the biggest enemy.In the mildew season in the south, the two ends of the lens barrel can be tightly tightened with impermeable plastic Bags. The desiccant (do not touch the lens) in the inside of the bag can be placed inside, and new desiccants are often replaced to keep the dry mirror dry.

(2) If there is dust such as dust on the optical mirror surface, gently blow the ear balls and do not blow it with a mouth to avoid splash splashing on the mirror;Layers and mirrors; do not touch the optical mirror surface with your hands. The fingerprints left will often corrode the mirror surface and cause permanent traces.If you accidentally wipe your fingerprints as soon as possible, a mixed fluid droplet of 50 % of the water -free ethanol and ether should be dripped on the clean skilled gauze, and gently turn to the mirror edge from the center of the mirror or counterclockwise from the mirror center.Wipe (you can only wipe it in one direction, you can't wipe it back and forth), and constantly change the skim cotton ball until it is cleaned.In addition to the usual attention of the Telescope mirror, cleaning should be cleaned from time to time. Do not use organic solvents to the lens to avoid damaging the diaphragm. For aluminum -plated reflex mirrors, try not to wipe as much as possible to prevent aluminum membrane damage or fall off.

(3) Portable Telescope try not to observe on the foggy forests, water and seaside. If it is not necessary to observe, you should wipe it as soon as possible after the observation.

(4) The reflex mirror surface of the reflecting Telescope should be coated regularly (1 to 3 years) to ensure that the reflector surface has a good reflection rate.

The maintenance and maintenance of large and high -end Telescopes is best to ask professionals in astronomy units to assist in.

2. maintenance of the Turn instrument

(1) The mechanical and tracking system of the Telescope is a high -precision transmission system, but because its speed is slow, it generally does not need to be maintained frequently. It is just according to the requirements of the instructions.); If the model of lubricating oil (fat) is different, please clean the original lubricant (fat) with kerosene and then add new lubricant (fat). Be careful not to put different types of lubricating oil (fat)Mixed use.Conditional units or individuals, if you can use it for a few years, ask professionals to re -clean, refuel, and adjust it will be very beneficial.

(2) The control system of the Telescope should be checked from time to time. When used, it should be operated strictly in accordance with the requirements of the instructions. Usually, water droplets, water vapor, and foreign matter should be prevented from entering the circuit part. The battery should not be removed for a long time.

3. maintenance of the electronic control system

The electrical control system of the Telescope is very different due to different models and functions, but the attention points to the use of maintenance are basically the same:

(1)Check whether the input AC voltage is the same as the rated voltage of the Telescope. When using the DC power supply, you should also pay attention to whether the rated voltage of the battery pack or battery is consistent with the requirements of the Telescope electronics control.

(2)In high -power driving circuits, please pay attention to the heat dissipation tablets of high -power tubes. Do not touch each other to avoid burning the Tube.

(3)Do not pull the trail and randomly cross all the power supply or electrical control cable to avoid disconnection.
