Maintenance of telescopes

Good or bad maintenance will also directly affect the life of the telescope

1. Use the telescope to pay attention to moisture and water, try to ensure that the telescope is stored in a dry, ventilated place to prevent mould, if possible, put desiccant around the telescope and replace it often (six months to a year).

2. For any residual dirt or stains on the lenses, wipe the eyepieces and objectives with the flannel cloth included in the telescope bag to avoid scratching the mirror. If you need to clean the mirror, you should use a skimmed cotton ball with a little alcohol and rub from the centre of the mirror in one direction towards the edge of the mirror and keep changing the skimmed cotton ball until it is clean.

3. Optical mirrors should never be touched by hand, the fingerprints left behind will often corrode the mirror surface, thus causing permanent traces.

4. The telescope is a precision instrument, do not drop the telescope, heavy pressure or other strenuous operation. When playing outdoor sports, the telescope can be fitted with a strap, and when not in use, the telescope can be hung directly on the neck to avoid falling to the ground.

5. Do not disassemble the telescope or clean the inside of the telescope by yourself. The internal structure of the telescope is very complex and once disassembled, the optical axis will change so that the imaging of the left and right cylinders will not overlap.

6. The telescope must be placed squarely, not upside down with the eyepiece. Some parts of the telescope are lubricated with grease and some parts are designed with oil reservoirs. If the telescope is placed upside down for too long or if the weather is too hot, the oil may flow to places where it should not.

7. Please do not bump the telescope against sharp objects to prevent scratching or soiling the objective and eyepiece.

8. Avoid using the telescope or opening the objective lens cover in bad weather conditions such as rain, snow, sand or high humidity (over 85% humidity), grey sand is the biggest enemy.

9. Finally, never use a telescope to observe the sun directly. Strong sunlight focused by a telescope, like a magnifying glass focusing light, can produce high temperatures of several thousand degrees, thus injuring our eyes.
