With the progress of The Times, people’s life has become better, from the pursuit of the material to the pursuit of the spiritual, the telescope is no longer a luxury, many people have their own telescope.  Although most people have such good telescopes, they have a problem with maintenance.  I wonder if the telescope needs maintenance?  So today, with the author, we will answer your doubts.  

1. Does the telescope need maintenance?  

Yes, the telescope needs maintenance.  Every telescope gets dirty.  Dirt on a lens or mirror scatters light, making a dark sky less dark and bright objects less clear — but not as much as you might think.  The right attitude towards a telescope means knowing how to take care of it and how to use it properly.  

2. How to maintain telescopes?  

Double simple mirror maintenance is also relatively simple.  It should be placed upright at ordinary times, carefully put when using, so as to avoid the displacement of the prism by the earthquake.  The lens is stained with dust, as far as possible with the hand knead rubber balloon blow clean, with flannelette or lens paper wipe, to prevent the lens is pulled hair, or damage coating layer.  Do not master the optical instrument maintenance technology, do not disassemble the binoculars, because their optical parts have been adjusted when leaving the factory, if disassembled, it is difficult to restore to its original state under amateur conditions.  

Dew often congeals in the binoculars during stargazing at night.  During the day, it should be placed in a shady and ventilated place to dry naturally.  To prevent lens mildew, had better collect binoculars in the drying box, the iron sheet biscuit box with good sealing sex Yi Ke is used, a few packets of drying agent are put inside the box, 3, 4 months update commonly.  

3. Telescope cleaning  

First, if there are particles such as silt on the lens, before formal rubbing, must be removed first, because they are harder than glass, may scratch the lens.  This can be blown open or lightly brushed off with a soft cloth.  

Second, find a clean cotton cloth or napkin (there are no hard particles in it, which won’t damage the lens and won’t scuffle easily).  

Third, look for medical alcohol.  If alcohol is not available, you can find the detergent you use to wash vegetables, and then dilute the detergent to 1/10 of an aqueous solution.  

Fourth, lightly moisten a cotton cloth or napkin with alcohol (or an aqueous solution of detergent), just enough.  Rub your lenses gently.  

Fifth, generally buying a telescope will give you a telescope lens maintenance package, suggesting that we make good use of these maintenance items.  

4. How do I store the telescope?  

The most important aspect of telescope storage is a warm and dry environment.  Do not store the telescope in a very hot attic or damp basement.  It is also important to always protect telescope optics (including eyepieces) with a dust cover or use a telescope storage case.  

If the telescope is not used for a long time, it is recommended to put it in a dry, ventilated, and cool place.  Especially in the south, the climate is humid.  This applies to the storage of all-optical instruments, including microscopes, camera lenses, etc.  

As precision optical instruments, telescopes should be avoided as much as possible from bumping and squeezing.  Telescopes are carefully tuned before they leave the factory.  Including military telescopes, all need to be well protected. Once the accuracy is damaged by collision and extrusion, it is necessary to return to the manufacturer to check the instrument again.  

Wherever you store the telescope, cover the optical components.  Usually, the simple approach is to add a dustproof cover in front of the lens tube, the focus tube plug, or cover with a small plastic bag.  If the telescope does not have a dust cover, or if the cover has been left for a long time, it is usually replaced with a good plastic bath.  

If your telescope doesn’t have a lid or is missing, a shower cap can be an effective duster.  It may not be pretty, but your mirrors and mirrors will thank you for your care with better images.  If binoculars have bins, use bins.  The case not only adds a second layer of dust protection but also protects the equipment from unexpected jolting collisions.  

The dark, damp glass of a telescope is a perfect breeding ground for mist and dew.  To prevent your telescope from becoming a petri dish with a lid, make sure all components are dry before storage.  Tilt the barrel horizontally to ensure that there is no moisture on the lens, mirror, or correction plate.
