Chapter Eighty-Five: Astronomical Mirrors

"Brother Meng, it's best to find another mold maker, and you have to prepare some good iron. Pen ~ fun ~ Pavilion www.biquge.info but," Gong Nian Huai shook his head, "Brother Meng, this matter is too risky, you better not come out." ”

"Gongshi, don't you have a gambling contract with Yan Shi, remember that the little one hasn't cashed it yet." Zhang Yan on the side reminded.

"Oh," Gong Nian Huai patted his head, "how did you forget this stubble?" ”

"Nian Huai, you made a bet with Yan Zuotou, why don't you know. What kind of bet, can Yan Shi listen to your orders? ”

"Haha, Brother Meng doesn't know anything, and the younger brother is also a person with apprentices now." Gong Lose Nian Huai didn't take the bet with Yan to heart, if no one mentioned it, Gong Lose Nian Huai really can't remember.

"Hey, Nian Huai, you are ruthless enough, a gunpowder competition, try to make an apprentice. Then what are you waiting for, send someone to summon Yan Shi over. Meng Zhijing's brows relaxed, and he could run away.

"That," Gong Nian Huai touched around, and found that there was no one in the courtyard to command.

"Gongzi Gongzi, I'll go for a trip, no matter how you say it, Yan Shi is also a leader, not to mention that it is still your apprentice, it is not appropriate for others to go." Zhang Yan owed his ass, finally stood up, and said a set of words.

"Okay, Brother Zhang, then there will be labor. Oh, Brother Zhang, don't be ridiculous, I don't think this person has a thick skin. ”

"Oh!" Zhang Yan responded and walked out quickly.

"How about Nianhuai, now install a clairvoyant mirror?" Meng Zhijing saw that everyone was almost gone, how could he still hold on, and he was about to move.

"Good. However, when Brother Zhang came back to complain, I didn't have long ears. Gong Nian Huai smiled, got up and walked towards the house.

"Brother Meng, what time is it today?" Gong Nian Huai asked casually.

"June 20, tomorrow is the beginning of autumn, what's wrong?"

"Liqiu?" Gong Nian Huai stopped and looked at the dark sky to the west. The beginning of autumn, if calculated in the solar calendar of the future, should be August 7 or 8. This is the first time I have come to this world to get a more accurate time positioning.

"I think of something, I don't miss it." Meng Zhijing glanced at Xitian with Gong Nianhuai's gaze, and asked casually.

"It's nothing, the little brother just feels that autumn is really coming." Gong Nian Huai sighed secretly and stepped into the room.

Meng Zhijing rushed into the house first, found a candle, lit the rope, lit three butter giant candles, and the room instantly lit up.

The two dragged the two boxes to the hall, and Meng Zhijing set out a large square table, which was the workbench.

Gong Nian Huai took out the frame of the telescope from the box and gently placed it on the table. Meng Zhijing stood at the table with his hands scattered, as if he wanted to reach out to help, but he didn't know how to intervene, more like he was worried that Gong Yi Nianhuai would accidentally fall off the frame.

Gong Yi Nianhuai originally wanted to install a clairvoyant mirror tomorrow, so when he looked at it with Fang Qiong, he didn't care about the size of the frame. Now I looked at the frame carefully, tried to adjust it, put the guide rail of the eyepiece box back on, tried again, and sure enough, the focusing device of the eyepiece was extremely smooth, and after trying the base again, there was not much vacancy, and the rotation was also very flexible.

Gong Yi Nian Huai was overjoyed, "Haha, Brother Meng, this frame is very good." Ah, don't mention it to Uncle Fang. ”

Meng Zhijing couldn't help but smile and nodded solemnly, "Well, Nian Huai is extremely right." ”

Gong Nian Huai lifted the box containing the lenses and put them on the table, opened them, and took out two small bronze mirrors, the mirrors were extremely bright, obviously made of fine grinding.

Gong Nian Huai picked up one of the mirrors and looked at the right angle, and sure enough, a complete square was reflected on the wall, but unfortunately the room was too small, and the candlelight could not compare to the sunlight, and it was impossible to try the distance.

There was also a small wooden box containing two glass-like lenses. Gong Nian Huai carefully took out a piece and looked closely, and sure enough, it was a standard convex lens. The crystal has been polished to a translucent light, and the veins on the palm can be clearly seen. Gong Nian Huai looked at it for a moment, couldn't put it down, took a small piece of paper and put it on the table, focused the lens on the candlelight, and a point of light appeared on the paper, trying to burn out the hole, obviously the temperature of the candlelight was very weak.

Meng Zhijing stared widely on the side, watching Gong Yi Nianhuai play with the crystal lenses, but he didn't dare to get started. I only keep the shape of the lens in mind.

Gong Nian Huai took out the two largest lenses in the box. These two mirrors are concave mirrors, and the surface is extremely smooth, and when you try it against the wall, the focal length seems to be about one meter.

Gong Nian Huai was relieved, his frame was just set at one meter, and with the reflective device, it was enough to fit this objective.

After being busy for a long time, Meng Zhijing couldn't bear it, so he looked at the mirror and didn't say a word, Gong Nian Huai didn't greet him, and he never said a word. Finally, when the candle burned out half of his body, Gong Nian Huai put all the lenses into the frame.

The next thing to do is to adjust the optical axis of the primary mirror, this step is not simple, but the adjustment device made by the deer carpenter is extremely ingenious, no, it should be that the picture made by Gong Nian Huai is very skillful. Gong Yi Nian Huai asked Meng Zhijing to make a move, Meng Zhijing was so excited that his face was slightly red, but he just stretched out his hands, so that Gong Yi Nian Huai saw it, and he was a little unbearable. They all shook like dead branches in the cold wind.

"Haha, Brother Meng, you can just use it as a bow and crossbow." Gong Nian Huai straightened his waist and stretched it, by the way, he loosened Meng Zhijing's nerves, he was too excited and nervous, his brain would spasm, and his muscles would become stiff and he would not obey him.

Meng Zhijing smirked, reached out, touched the frame, and exchanged feelings first.

With Meng Zhijing's help, it is not difficult to adjust. After the main mirror was adjusted, Gong Nian Huai pointed the frame against a candle, and put a small piece of paper one meter in front of the frame, and a small dot appeared on the paper, which was the focus point of the concave mirror, which was the same principle as the sun cooker.

Next, it's time to adjust the combination of the mirror and the eyepiece. The reflector can be slid up and down in the main frame, and the eyepiece device is also extremely reasonable,

Gong Nian Huai was busy for a while, and felt that it was almost over, so he and Meng Zhijing pushed the table, came to the door of the house, and pointed the telescope at the sky in the distance.

Meng Zhijing frowned and asked puzzledly: "Nian Huai, this is also the Thousand Miles Divine Mirror?" ”

Guo Bencong fiddled with the frame and said, "Of course it is." However, it is a mirror that allows you to see the scenery far away. Stronger than the Lord's Fight. ”

Meng Zhijing said: "How far can you see?" ”

Gong Nian Huai was stunned when he heard this, and wanted to say a billion light years, but he felt that it was really inappropriate, thought for a moment, and said, "About a few hundred miles." ”

Meng Zhijing was startled, and said to himself: "Wouldn't you be able to see Xiangyang?" ”

Gong Yi Nianhuai smiled: "If you put this Thousand Miles Divine Mirror on the top of the mountain, it is normal to see Ezhou." As he spoke, he pointed the lens barrel at a distant target.

Looking through the eyepiece, I was dazzled, and I couldn't see anything clearly, and Gong Nian Huai remembered that the whole mirror was still open.

Gong Nian Huai turned around and took the black cloth and black paper that had been prepared. After being busy for a while, the cylinder wall of the telescope has been surrounded by black cloth.

The eyepiece tube was also covered by black paper, and when I looked through the eyepiece again, I could vaguely see a blue color, like a treetop in the distance.

Gong Nian Huai was busy in front of the mirror for a while, finally straightened his waist, took a long breath, and looked at the expression that seemed to be extremely satisfied, turned his head to glance at Meng Zhijing who was following him, and said with a smile, "Brother Meng, come and see." ”

Meng Zhijing glanced at the already dim courtyard and asked suspiciously, "Can this still be seen?" ”

"Brother Meng, look at the sky." Gong Nian Huai looked up at the sky, and above the dim middle sky, a clear green dome arched. A few stars shimmer with a golden halo, like trumpet flowers a hundred meters away.

"Look at the heavens?" Meng Zhijing looked at the angle of the objective lens, "Can you see the stars clearly?" ”

"Brother Meng, please try!" Gong Nian Huai stretched out a hand very bloodyly and made a gesture of please.

Meng Zhijing approached the eyepiece both puzzled and excited, "Haha, what a big moon." Nianhuai, come, the moon has risen so high. ”

"Brother Meng, today is June 20th, the moon hasn't come out yet!" Gong Nian Huai hugged his arms and stood beside Meng Zhijing, with a wicked smile on his face.

"Ahh Meng Zhijing raised his head and looked at the sky, except for a few stars, where was the moon?

"Nian Huai, this," Meng Zhijing glared at the sky and raised his hand to the sky, stunned and inexplicable.

"I'll see." As he spoke, Meng Zhijing leaned closer to the eyepiece again, "Huh! The moon is out again. Nian Huai, this, what's going on? Meng Zhijing looked like a ghost, staring at Gong Yi Nianhuai, with a puzzled face.

"Hey, Brother Meng, what's so strange about this. If you look at the jars in the yard, they are all jars of the same size, and the ones that are far away are smaller, and those that are closer are larger. It's the same with the stars, the clairvoyant mirror shortens the distance between the stars, and it becomes bigger. Gong Yi Nianhuai spread his hands, and he could only explain it like this.

"Oh!" Meng Zhijing stared at the jar in the courtyard for a long time before nodding ignorantly, understanding that it was already very gratifying.

"Nian Huai, cough, um, do you want to try it in the open field?" Meng Zhijing rubbed his hands, circled around the clairvoyant mirror, and watched non-stop. It's like a kid who just got a fun toy.

"Oh, yes. It's just a little heavy, and it's nice to have a small cart. "Gong Nian Huai doesn't want to run around with dozens of pounds of things on his back. Qiongzhou yellow sandalwood is not light, plus crystal and other polished lenses, the weight is too overwhelming.

"Little cart, yes, yes," Meng Zhijing rushed out with a sound, probed, and turned back, "Nian Huai, Niu Ben is back, just using his car." Haha, there are housekeepers too. Niu Ben, come here, push the cart over, oh, let's hold it, these cans are too much of a hindrance. ”

Meng Zhijing ran back to the house, picked up the clairvoyant mirror and walked out.

"Brother Meng, be careful, step." Gong Nian Huai hurriedly ran to the side to take care of it, and the jade was broken before the teacher came out, which was too worthless.
