Conan: The Mechanic

I don't know how long it took, but Chiba's hand that wasn't clasped with Haibara Ai, who was just quietly feeling each other's breath and the warmth from her palms in the dark, suddenly moved. "I left the blanket open, otherwise I wouldn't be able to observe."

"You have to put your eyes on this astronomical telescope, right?" Haibara asked while listening to Chiba's hand moving the blanket.

"I connected a periscope to the end of the astronomical telescope yesterday, and I just need to stick the periscope in - the angle of the astronomical telescope itself can also be controlled by the transmission handle I connected to it." Chiba said this and opened the blanket After taking a small mouth, he blocked his body between the air vent and Haibara Ai. "Wait a minute, I'll pull the handle and periscope in."

After a while, Haibara Ai found a single-tube periscope pulled in front of her. "This is your periscope tube, just use a periscope like an observer on a submarine." When Haibara held the periscope tube with both hands, she put her eyes on the periscope tube - what caught her eye was the bright starry sky .

"I'll look at the location..." Qianyu also pulled another periscope in her direction and began to observe the starry sky. "Well, looks like it needs to be repositioned."

Saying so, Chiba began to turn the handle in her hand, and Haibara Ai saw the star map in her eyes slowly moving. After about 30 seconds of spinning, the screen stopped.

At this time, the snow-white Jupiter appeared in the center of the field of vision. The size of this big guy was so large that it almost occupied the entire field of view of the telescope.

"How many times did you zoom in?" Haibara asked sadly.

"500 times," Chiba replied. "Fortunately, we are on this airship, otherwise, even if we zoom in to this multiple, we won't be able to use it."

For telescopes on Earth, magnification is not the main factor that determines the quality of observations. What determines this is actually another concept - seeing. This concept represents the quantitative degree to which the observation target is disturbed by atmospheric turbulence and begins to blur and flicker. Although this concept does not determine to what extent the observed planet will be magnified, it will directly determine the observed image. how clear. For ordinary ground observers, seeing limits the quality of their observations, and professional-level astronomical telescopes often cannot obtain good observation results. Although it is said that the United States has begun to experiment with a new technology called adaptive optics technology, which is said to be effective in the problem of seeing, but this technology is still not popular, and it is far from the popularization of civilian observers in terms of cost and technology maturity. Even more distant.

However, thanks to this airship, they will not be overly troubled by the earth's atmosphere-their flight altitude has stepped on the troposphere, and the atmospheric conditions of the stratosphere are far from the troposphere below it. So moody. As long as their astronomical telescope can theoretically provide that clear effect, then they can see that clear effect.

Just like now, the 500x magnification provided Haibara Ai and Chiba with a clear picture that neither of them had ever seen with their own eyes before - if it was under the poor seeing conditions on the ground, they might also be able to see it like this Huge Jupiter, but the edges are probably constantly fluctuating and quite blurry. It is almost impossible for them to observe in such bad astronomical conditions. Although it is very conspicuous in the previous collision of A debris, it is still not conspicuous enough to overcome The harsh seeing conditions on the ground.

Of course, magnifying to 500 times also has disadvantages, such as...

"Is this thing moving?" Ai Haibara asked with some doubts.

"Yes," Qianyu nodded. "I haven't mounted the motorized part of the handle to the spare motor they gave me - since we don't need to keep the focus steady for as long as those photographers do, there's no need to put this harder to mount. Get something up."

As they faced, since Jupiter rotates a little more than 30 degrees per year, a magnification of 500 is equivalent to a deflection of 1.8 arcseconds per second, which results in a high magnification view in the long run would keep drifting, and would make it impossible for telescopes that don't rotate with the stars to get high-quality images with long exposures. Of course, for someone like them who only needs to watch for about 30 minutes, that's not a problem.

"Do you think it's too dark?" Qianyu asked suddenly.

"Fortunately..." Haiyuan Ai shook his head. "Although it is not very bright, it is barely enough."

All observations would be fairly well-contrasted if it were a processed image like the one shown in a movie screening room, but in fact the images captured by the high magnifications are quite dim - for example, at 40x magnification Jupiter is a bright golden ball with two dark bands around it, but at 400 times it's probably just a dull white ball with four bands. Chiba's auxiliary unit can enhance the overall effect of image observation at the expense of a little detail accuracy by enhancing contrast, but Haibara Ai can't do it with the naked eye - fortunately, it doesn't seem to affect her visually. The observation experience of ~www.readwn.com~ At this moment, the G debris appeared on the edge of the field of view of the astronomical telescope.

"Here it is." Qian Yu whispered softly.

The reason why Qianyu brought Hui Yuanai to watch the collision of this fragment is not mainly because of the difficulty of observation, but because this fragment is the largest fragment among all the fragments of Sumei Kelevy. A shard even bigger than Shard A, which produced the impressive crater before. Before the collision, when Qianyu was preparing for the whole process, he had already chosen to observe when this debris collided with Jupiter, because no matter what the impact of the collision will ultimately be, the G debris will be the interpretation of all this to Jupiter. The most perfect piece.

At the same time, after the G-shard has quietly submerged into Jupiter's apparent disc, it also means that the most magnificent scene in the collision of the entire Shoemaker Levi is about to appear.

Chiba felt a warm touch from her fingertips again, and then she bent her palm almost without any reason, so that several fingertips fit together with Haibara Ai's fingertips.

At the same time, a fireball larger than the one produced by the previous A-fragment collision appeared behind Jupiter.

Chiyu's hand felt that Haibara Ai's hand seemed to be probing towards him, so she turned her hand over and placed it under Haibara Ai's hand, and the two of them looked at the fireball in the telescope.

"It's really spectacular, isn't it?" Haibara Ai suddenly said. "It's a lot more immersive than watching a video over there."

"Of course," Qian Yu's mouth twitched slightly. "Otherwise why would I bring you here?"
