This kind of telescope has strong light power, large field of view and small aberration, which is suitable for taking large-area photos of the celestial region, especially for faint nebulae. The Schmidt telescope has become an important tool for astronomical observations.

The astronomical telescope that Jefferson and Parker commissioned was still based on this principle, but with major improvements in modern technology and greatly improved performance.

According to the commissioning requirements, Parker observes twelve points, compares them, and derives the parameters he needs, and then determines the performance of the telescope based on these parameters. This is a necessary procedure for the acceptance of newly installed telescopes.

Parker was in charge of the acceptance work, and Jefferson, who was blinded by the old man, was in charge of controlling the computer and recording the relevant data.

By this time, Parker had completed seven test items and was moving the telescope to the next position.

A multicolored disc flashed in the mirror, and Parker thought he was looking at it, and after thinking about it, he turned the lens back again.

Returning to the place in his memory, the sky was empty and there was no trace, and Parker couldn't help but hesitate: Wrong, right?

After all, one millimeter on the ground, tens of thousands of miles in the sky, once you miss it, it is difficult to find it.

Out of the rigor of a scientist, Parker searched the area again, but found nothing, so he turned back to Jefferson:

"Teacher, did you see anything just now?"

Jeff a**Ben** read. Novel ybdu sen opened his confused eyes, people over fifty, and they really lacked energy, not to mention that the acceptance of a telescope was not a complicated job, so he fell asleep just now.

"Look at what? Is there something? ”

Parker knew Jefferson's physical condition and sat down next to the computer with a smile:

"Heh, a halo, maybe I'm wrong."

So the two of them gathered around the monitor, and Parker began to play back the data.

The picture shows the past frame by frame, and the two of them watch it meticulously.

When they saw the ninth minute and ten seconds, a disc flashed in the frame, and the eyes of the two immediately widened.

"Return, come back, it looks like there was something just now."

Parker slowly recalls the image, and finally, the disc reappears on the screen.

The position of the disc should be 3,000 kilometers northwest and more than 10,000 meters above the ground.

From the outside of the graphic, it is not so much a disc as it is a combination of halos, the outer ring and the inner ring, layered together, colorful, very brilliant.

This aura appeared for a short time, and it flickered and disappeared in the air, and if it wasn't for Parker's coincidental meeting and just moving the telescope in that direction, no one would have been able to spot it.

The image quality is average, and the vision is not particularly clear, and the two of them have their eyes sour, and they still can't analyze a reason.

"Are there any satellites passing by?"

Parker checked the information and shook his head regretfully: "No, the Jianbing-2 satellite passed by there five minutes ago and missed it." ”

The two of them analyzed the spectral principle again, but still found nothing, and there was nothing special about this aura, which could determine that it was not an entity.

Jefferson lay down regretfully on the back chair:

"Well, maybe it's just ordinary light refraction, similar to those UFO legends."

………

Thousands of miles away, Zhang Binhui, Ling Doudou, and Mo Yingxuan stood up suddenly, that piece of Caixia was too familiar, and that was where the little baby set up a teleportation array.

Ma Tianyuan, He Qiliao and the others were chatting enthusiastically, when they saw that the three people on the other side suddenly stood up, turned their heads to look at the sky, and they also looked at the sky curiously.

Seeing that the night sky is full of stars at this time, today's night is indeed good.

At the top of everyone's heads, a colorful halo suddenly appeared, which looked the size of a desktop from a distance, colorful and very beautiful.

Ma Tianyuan praised with a smile: "What a beautiful gift, it can be played so high." ”

Zhang Binhui turned around and said goodbye to everyone with a smile: "Three, you are full of food, I am going to go out for a walk with my two cousins, no one wants to be a light cannon, right?" ”

Ma Tianyuan laughed, He Qiliao was about to drool with envy, and Huo Shengnan was a little disdainful.

The three of them stepped out of the hotel and immediately flew into the sky incognito.

"What's going on? It seems to be the location of the teleportation array. ”

Mo Yingxuan frowned: "It's hard to say, looking at this light, it's a bit like the collapse of the teleportation array, I don't know until I see it, I'm afraid it's not a good thing." ”

The three of them were very fast, and in the blink of an eye, they rushed to the high altitude where the teleportation array was.

At this time, where was there still a teleportation array in the air, and even that enchantment was destroyed.

The air was scattered with escaping spiritual power, and there were also some fine jade powders floating in the air, which were used to construct the teleportation array. The collapse of the teleportation array was severe, and all components were blown into powder.

Zhang Binhui has not undergone the corresponding training and can't see any problems, but the two girls have serious expressions, and they are walking around to investigate, as if there is something important hidden in it.

The red light of the jade ring on Mo Yingxuan's wrist flickered, and the frost on her face was about to turn into water.

"This was the alien who did it, and it destroyed our teleportation array."

This sentence startled Zhang Binhui, what did the alien do? It has just been hit hard, how dare it take the lead?

Ling Doudou flew over from the other end of the original enchantment, and she was also wearing the same jade ring on her wrist, the situation of the jade ring was the same as Mo Yingxuan's, and the red light was very dazzling.

"Alien."

The three of them all stood still in mid-air, this alien action was very strange, destroying the teleportation array, what was its purpose? Don't you want a cultivator to teleport over? Or do you want the cultivators who have already come over to be separated from the earth?

Zhang Binhui said his thoughts, and the two girls were also thinking about this issue.

"It stands to reason that there is not only one teleportation array on the earth, if this is destroyed, we can travel to and from the earth through other teleportation arrays, and the purpose of the alien cannot be achieved."

"Where's the other teleportation array? Can you tell me the location? ”

Ling Doudou clicked on the bracelet, and a three-dimensional pattern appeared in the air.

Looking at the location of the logo on the map, Zhang Binhui frowned. This map marks the location of the teleportation array very clearly, but looking at the light spots on the map, Zhang Binhui always feels that something is wrong.

A little spiritual light crossed Zhang Binhui's mind, and he shouted suddenly:

"Ah, I see, the purpose of the alien appearance is to destroy the teleportation array, and the second teleportation array is very dangerous."

Hearing this, the two girls looked over: "Why?" ”

"Look, where is this teleportation array?" Zhang Binhui pointed to the map: "It is located on the passage of the original alien to the north, this alien is not going north for nuclear waste, it is going towards the teleportation array." ”
