[Use of astronomical Telescope] How to use the astronomical Telescope to use the correct use step and guide

1. Install a astronomical Telescope according to the instructions.

2. Regarding the focus of the Telescope and the calibration of the cross -line mirror

Loose two fastening screws on the eyepiece.Take out the low -duty mirror and put it on the eyepiece to pick up the cylinder, and then tighten the screw.The adjustment of the focusing knob can obtain a fuzzy image of an object A in the distance, and then slowly adjust the coke knob back and forth until the object image is clear.The Telescope has accurately adjusted the focal length, and now it can be observed with a star -seeking mirror.If the astrology mirror is not at the focal length, turn the eye mirror until a clear scene appears.When the object of object A you see on the Telescope is not in the center of the star mirrors, according to the following method: tighten or release the screw on the star -seeking mirror support, so that the star -seeking mirror up and down, left and right workers, left and right workers, left and right workers, left and right workMove obliquely.When the object of the object A appears in the center of the cross line, your star -seeking mirror is ready, and finally the three screws are tightened.Then replace the low -power mirror with a high -power mirror and repeat the above program.If the center of the image observed under the maximum mirror and the cross -line center of the star -seeking mirror, your star -seeking mirror is adjusted.Now you can quickly find the celestial body you want to observe.In extremely special circumstances, star -seeking mirrors may need to be adjusted.

3. precautions

A. Under any circumstances, first look for objects with a star -seeking mirror, because the perspective of the star -seeking mirror is greater, which can greatly accelerate your coarse tone.

B. Under normal circumstances, first install a low multiplier mirror to gradually increase the multiple you need, and you need to make the necessary focus when you change the mirror.

C. Don't be troubled by the upper and lower, left and right images that you see, this is a normal situation for astronomical Telescopes.

4. Effective observation notice

If the Telescope gets outdoors for the first time in air with lower indoor temperature, it must be used for a few minutes-because the temperature difference will make the lens blindfold.This phenomenon will disappear after 15-20 minutes.If your eyelids or fingers touch the eyepiece, the cloth that can't afford the hair will be gently wiped to see the mirror to prevent blurred images.It takes about 30 minutes to enlarge your pupils to adapt to darkness, so use a Telescope at night. After half an hour, you can see a much dark celestial body.

5. Various factors that may affect the observation results

Observation results are not all taken in the optical properties of the Telescope, and many factors also affect the quality of the image.

A. The atmosphere surrounded by the earth is always moving. This kind of atmospheric movement and rotation will cause bad images at a high rate. Perhaps after a few nights, the observation will improve.

B. The heat on the surface of the earth will also cause the fluctuations of the air and make the image distort and deform, resulting in poor observation.

C. The observation angle of the Telescope and the star and horizon has a great impact on the observation effect: if the star body is close to the horizon, the goal will be blurred.

D. Pollution of light sources: use your Telescope (such as under street lights, under room Lights, etc.) as much as possible in a light -free environment, high -mortar astronomical Telescope is very sensitive to light.Even more obvious, it seems that many stars will disappear over the urban area.

E. Moonlight may also be another factor that affects observation. The dazzling full moon or bright moonlight will blur the nearby stars or planets, and the moon itself is the best observation state between darkness and Tianming.

f. Try to avoid observation from opening the window (let alone observation of closed windows), especially in the cold season, the indoor and outer temperature difference can be worse, which will make the observation quality worst.

G. The cloud layer accumulated in the sky cannot penetrate the observation, but this cloud will often move.

H, star flashes are caused by air convection, which will also affect observation.

Remember, in any case, do not directly observe the sun through a star -seeking mirror or main lens barrel, otherwise it will seriously damage your eyes.

1. How to make green dill Nutritional soil

1. Garden soil: It has a strong water retention and Fertilizer capacity. It can usually be seen in vegetable gardens, fields or roads, and is slightly acidic.

2. Rotten leaf soil: The texture is very loose, and the water retention Fertilizer is very good. It comes from the surroundings of the tree roots. Generally, it is formed after deciduous deciduous after a long time.

3. Sand and soil: The breathability is very good, and it contains many trace elements. After the absorption of plants is conducive to growth.

4. Square: The breathable drainability is very strong, and it can mix it into the soil.

5. Putting the above -mentioned mixed preparations, you can cultivate the green dill.

2. precautions for the production of green dill Nutritional soil

1. Pay attention to its drainage and breathability of homemade green dill soil. If the breathability is not good or the drainage is slow, it is easy to produce water, and the root system is easy to rot.

2. Green Luo likes acidic or neutral soil. If the use of alkaline soil breeding is not conducive to its growth.

3. Many flower buddies like to use pond mud, and think that it is fertile. This soil is not suitable for green dill growth.Because, it is very close, the breathability is very poor, and it is easy to rot with the pond mud.

Third, what kind of Nutritional soil is used in green dill

1. If you want to cultivate the green dill, it is best to choose nutrient soil to cultivate. This is easy to buy. Generally, do not make it. You can buy it directly. The price is relatively cheap.

2. Generally, when the Nutritional soil is used to cultivate the green dill, some stones or granite can be added to the nutrient soil, which can ensure that the soil's breathability is better.

3. In addition to nutrient soil, you can also choose to use sand soil. Do not use other soils, because the air permeability of sand soil can be used to breed green dill.

4. During the breeding, the soil will appear on the soil. Generally, you choose to loosen the soil regularly. It is better to choose the soil once a month to ensure that the soil is loose.

5. During the breeding, the nutritional content of the soil will be absorbed. Therefore, fertilization is needed. Generally, fertilization is used every 2 months. You can choose Organic fertilizer fertilization.

6. If the Green Luo wants to change the basin, the soil of the best root can be changed together, so that it can avoid the phenomenon that cannot be adapted because of changing the soil.

Fourth, what Nutritional soil is the green dill cuttings

1. Great flower raising soil

flowers and friends usually use universal soil on the market. Xiaobian also bought nutrient soil on Taobao before. This kind of soil may not keep up with nutrition. Although the green dill has not high requirements for the soil, the fertile humus soil can be.It is right to grow flowers with loose pot soil, so it is usually matched with Nutritional soil.

2. Prepare Nutritional soil by yourself

It is generally used by self -matched nutrient soil, pine needles and garden soil, as well as perlite. It can be uniformly mixed with a certain proportion.Rooting and germination.

3. The wonderful use of eggshells

Because eggshells are rich in calcium and phosphorus, they can avoid yellowing leaves, and it is also good for the growth of green dill. Green lobes can be burst into pots. flowers can add some eggshells to Nutritional soil.

4. Cutting method

You can find a strong green dill branch, and then put the branches of the branches horizontally in the soil, and then after a while, the green dill can take root and rush into a large pot.

How to raise red worms

1. Breeding conditions

When breeding red worms, prepare a glassware, then put the selected red worms into it, and then inject clean and sterile natural water. If you want to use tap water, it is best to place tap water in the sun 2-3God, remove the chlorine gas in it to prevent red insects from growing poorly.

2. Control light source

The growth of red worms is inseparable from light. Lack of light sources can cause red worms to breathe and suffocate death. It is best to hang a 5 -watt Light bulb above the container to provide adequate light irradiation to the red worm to make them free.Breathing, healthy growth.

3. Water quality regulation

In the process of breeding red worms, you need to replace the water once a day to keep the water clean. In the process of changing water, clean the red worms and containers to clean the mucus to avoid breeding bacteria. It is best to control the depth of the breeding water.About 3-5 cm, deepen the water level at night, playing a warmth.

4. Feeding bait

Red worms mainly eat Organic fertilizer, and like some sour, sweet feed.In general, you need to be fed once every three days.You can use rice bran, sludge, pigeon dung, sawdust and other fermentation into feed.

5. Breeding management

Natural air flow should be performed in the breeding venue, and it can be exposed to the air, which can effectively improve the oxygen content.When the temperature is too high, you can use some artificial methods to increase the oxygen content of the breeding venue. When the temperature is below zero, frozen phenomenon will occur.At this time, they are easily frozen to death. They can use some other warm measures to reduce the icing of the water surface so that they can effectively grow them.

How to save time for red worms

1. Pick up insects

First, the bugs I bought are as much as I have just entered, so that they can be fed for a long time and can not die for a long time.

2, density

The density of insects should not be too large. If the density of the bugs is high, it is easy to die. Generally, it is raised with one to two or two cm stainless steel pots. The density is just right and the water is basically full.

3. Change water

The water needs to be changed every day, and placed in a cold place. If there is no cold place, place it in the shade window sill near the window.board, this can be insulated. It is best to keep the water of the red worm. The water temperature in the water in the pot is close, and the worm is easier to live.

4. Wash

The first is to wash the pot. After changing the red worm into the sieve every time the water is changed, the basin must be washed with water. At this time, some of the pots will be stained on it.Go down, rinse the pot. The second is to wash the insects, connect the water from the pot, and rinse the bugs in the sieve with water with water, and the mucus and dirty things on the insects.

5. Others

Pick out the dead bugs before changing the water or before changing the water to ensure that there is no blood water in the water polluting the water.

Running marathon and off -road Running are two very different experiences. The former track is more stable and the latter is more challenging.Various equipment.Of course, there are many differences between the two. For most people, the most direct difference may be on buying running shoes.

Ordinary running shoes

From the perspective of the outsole, the outsole is generally covered with the entire sole, which is covered with a variety of special patterns. There may be many grooves in the middle. Most of the colors are black and other colors.3-5mm EssenceThe main function of the outsole is to play a wear -resistant and non -slip effect during the direct contact with the ground.The outsole material is generally carbon -containing rubber. This rubber is more wear -resistant, and the anti -slip effect and weight are also ideal.

Off -road running shoes

Cross -country running shoes are shoes specifically for off -road competitions and training, with weight between ordinary running shoes and hiking shoes.Compared with ordinary running shoes, it pays more attention to protection. For example, the soles are designed for different terrain design, such as gravel pavement, mud roads and other roads. useTPU Inject the toe to prevent the toe from being hit by rocks, etc.; the upper is more tough to prevent being scratched. Some styles even provide GTX waterproof coating; the shoelaces will use a fast shoelace system or a shoelaces to collect Bags. This is mainly to prevent the lace from being hung up.

Hiking shoe

The rigidity and abrasion resistance of the soles of the shoe shoe is very good.For off -road running shoes and hiking shoes, hiking shoes have low gangs, medium gangs, high -top models, and various types have their own advantages.The low -end models can be designed for a large stride. Generally, the sole is soft and there is no side support.Self -heavy, the price is relatively low, it is very suitable for a small load, walking on a flat rural road or mountain road; and the middle gang's shoes are wrapped in the ankle, the sole design is more abrasion, the rigidity is greater, but it can be bent vertically to adapt to adaptationWalking for a long time.The shoe has a protective effect on the ankle and can reduce the impact on the ankle. For high -gang hiking shoes, it is suitable for the steeper and more complicated terrain of the route. The shoe help can protect the ankle well.Powerful supporting effects, in addition, the waterproof performance of the shoe will be much better.

Off -road shoes As well as running shoes As well as Hiking shoe What is the difference between the three

1 , running shoes are only suitable for us to wear, run, and exercise. If we want to run a marathon or small load in the wild for a long time, we can choose off -road shoes.It is more appropriate to choose hiking shoes if the terrain is complicated and rugged or long -distance.

2. Off -road running shoes are suitable for walking and Running on non -cement land, while hiking shoes are suitable for complex terrain such as cement land, mountain roads, and Skate landforms;

3. The off -road running shoes are well supported. The supporting shoes were supported by the off -road shoes, especially the low -top and middle -gang shoes;

4. Off -road running shoes are suitable for small load -bearing Running, and hiking shoes can't do this.Suitable for high negative hiking shoes is not suitable for Running, otherwise it is easy to cause typhoid fever to the feet, such as bubbles.

In any case, there are still differences between off -road running shoes and hiking shoes and running shoes.In actual purchase, we need to choose off -road running shoes and hiking shoes in combination with different situations, and will receive more effective results.

What are the types of fishing life jackets?

1. Classified according to the occasion of use

It can be divided into two types of life jackets and Ship fishing.

2. Divide the buoyancy material

(1) Bloating material life jacket: It is mainly divided into two PAC buoyancy, which is softer to pinch.a little.

(2) Inflatable life jacket: The compressed carbon dioxide gas is breathable and inflatable to the inner biliary.It can also be divided into automatic inflatable life jackets and hand -puzzled life jackets.

(3) EVA foam life jacket: It uses the EVA foam material inside, which is compressed by 3D stereo molding, and its thickness is about 4 cm.

3. Classified by wearing

It can be divided into sea fishing neck -hung life jackets, sea fishing waist bag -type life jackets, and sea fishing waist Hanging life jackets.

What is the difference between fishing life jacket and ordinary life jacket

Sea fishing life jacket belongs to the category of life jackets, but also has its own unique product characteristics:

1. Easy to carry

Sea fishing climbing, climbing, navigation, swimming, etc. are common. The equipment weighs 50 or 60 pounds. Sea fishing users must climb away on the reefs and ask the sea fishing life jacket to be easy to carry!This is different from ordinary life jackets.

2. Small volume and convenient wear

It does not take up the place, it is easy to store, take it, it is convenient to wear, it does not take time, affecting fishing and fishing.

3. Not subject to action restrictions

It does not affect the play of fishing skills. After the fishing life jacket is worn, it does not affect the performance of people's movements, and let the fishing sprinkle freely, without a sense of restraint.

4. waterproof pocket

You can store it with waterproof pockets, and the sea fishing life jacket is equipped with waterproof pockets, which can be carried with bait, mobile phones, etc.

5. Following the buoyancy standard

Provide sufficient buoyancy. If you accidentally fall into the water, you can provide a sufficient buoyancy life jacket to make the human body float on the water without drowning.

6. Fortune to discover rescue

There are 3M anti -light films, for help whistle, etc. The fishing life jacket designed for the fisherman not only has the function of ordinary life jackets, but also has a pocket device of reflective and light -emitting warning bar and the same as fishing vest.Putting small fishing accessories for enough space and location can be described as two birds with one stone.

How to buy fishing life clothes

1. The surface of the life jacket is mostly water -resistant and breathable materials. In addition to paying attention to their buoyancy parameters, fishermen should also pay attention to whether there are damage to the junction interface and other places to prevent gravity without gravity.

2. Generally, a pair of oval glowing body on the chest or shoulders of life clothes is mainly used for maritime rescue to facilitate the discovery of the target. Therefore, you should pay attention to whether to open the sewing when choosing, and then consider the color blending fabric.

3. Regardless of whether you are fishing or fishing, sea fishing life jackets should try to choose more bright colors such as red, yellow, orange, etc., because once the fishermen are accidentally falling into the water, it can make the rescue easier to discover rescue in time.

4. When choosing a life jacket, you don't have to choose too advanced ones, but you must choose appropriately according to your weight.

The use and maintenance of fishing life jackets

1. From the beginning of leaving the land, we must wear a sea fishing life jacket to prevent falling into the sea.Most people are paralyzed, ignoring the important role of sea fishing life jackets, thinking that they have good water properties and do not need to wear sea fishing life jackets.In fact, after all, the sea is not land, waves, vortexes, reefs, bad weather in mutation, there may be danger at any time. Not only is the water properties good, you can have high pillows without worry.Needless to say.Therefore, when you are fishing in the sea, you must wear sea fishing life jackets at sea.

2. Do not perfunctory when wearing the life jacket. The two insurance bands at the back of the lower rear must pass through the legs.To prevent the life jacket from falling off from the head during water falling.Please be sure to tighten your thigh Belt, zipper or lifebone. When the equipment is incomplete, the life jacket will fall off or disrupt the body balance and cause danger.

3. There is also a life -saving whistle in Lidar, which is normally in the life jacket, which can make a whistle when the surrounding environment is bad and vision is not good.

4. In order to ensure its life span, you should use a brush to brush the inside and outside after each use, then rinse with water and dry it in the ventilation.When not in use, avoid direct sunlight and keep it in a good ventilation place. In addition, it will reduce its performance when it is wet by water or sweat.

5. As a cushion will reduce the buoyancy or cause deformation and deterioration, please absolutely avoid.Washing the paddy cotton will cause a decrease in buoyancy, please try to avoid it.

6. The recommended life is not more than two years.
