I don't know how long it took, but the hand that was not clasped with Gray Yuan's mourning, which was just quietly feeling each other's breath and the temperature from the palm of his palm, suddenly moved. "I'll open the blanket open, or I won't be able to observe."

"Look at this telescope, you have to stick your eyes on, right?" Gray Yuan asked as he listened to the sound of Qianyu's hand flicking the blanket.

"I attached a periscope to the end of the telescope yesterday, and I just had to stick the periscope in – the angle of the telescope itself could also be controlled by the drive handle that I attached it." As she spoke, Qianyu opened a small opening in the blanket, and then blocked her body between the wind and the gray plain. "Wait a minute, I'll pull the handle and periscope in."

Moments later, Gray Yuan Ai found a single-barreled periscope pulled in front of him. "This is your periscope tube, just use a periscope like an observer on a submarine." When Gray Yuan Wai held the periscope tube with both hands and pressed his eyes against the periscope tube, he was greeted by a bright starry sky.

"I'll look at the location...... "Qianyu also pulled another periscope in his direction and began to observe the starry sky. Hmm, looks like we need to adjust the position. ”

Saying this, Qian Yu began to turn the handle in his hand, and Gray Yuan Ai immediately saw that the star map in his eyes was slowly moving. After about 30 seconds of rotation, the screen stopped.

At this time, the snow-white Jupiter appeared in the middle of the field of view, and the size of this big creature was so large that it occupied almost the entire telescope's field of view.

"How many times did you zoom in?" Gray Plains asked.

"500 times," Chiba replied. "It's a good thing we're on this airship, otherwise we wouldn't have used it even if we zoomed in to this multiple."

For telescopes on Earth, magnification is not the main factor that determines the quality of observations, but rather another concept – visual acuity. This concept represents the degree to which the observed target begins to blur and flicker due to atmospheric turbulence, and while it does not determine how magnified the observed planet will be, it does directly determine how clear the observed image is. For the average ground-based observer, the degree of vision limits the quality of their observations, and the availability of professional-grade astronomical telescopes often fails to obtain excellent observation results. Although the United States is said to have begun experimenting with a new technology called adaptive optics technology, which is said to be effective in terms of visual acuity, this technology is still not widely available, and it is far from being popularized at the level of civilian observers in terms of cost and technical maturity.

But, thanks to this airship, they are not overly troubled by the Earth's atmosphere, which has already trampled the troposphere under their feet, and the stratosphere is far less moody than the troposphere beneath it. As long as their astronomical telescopes can theoretically provide that clear effect, then they can see that clear effect.

Just like now, the 500x magnification gave Gray Yuan and Chiba a clear picture that they had never seen with their own eyes before—if it were in the poor visual acuity conditions on the ground, they might have been able to see such a huge Jupiter, but the edges would probably be fluctuating and rather blurry, and it would have been almost impossible for them to observe the kind of A-fragments that had occurred in such poor astronomical conditions, although conspicuous, but still not conspicuous enough to overcome the poor visual acuity conditions on the ground.

Of course, there are drawbacks to zooming in to 500 times, such as ......

"Is this thing moving?" Gray Yuan asked with some confusion.

"yes," Chiba nodded. "I haven't attached the motorized part of the handle to the spare motor they gave me – because we don't need to stay in focus for as long as those photographers do, so we don't need to put this harder thing up."

As they were facing, because Jupiter rotates a little more than 30 degrees per year, 500x magnification is equivalent to a 1.8 arc second deflection per second, which causes the high-magnification view to shift in the long run, and prevents telescopes that don't follow the stars from taking long exposures to get enough quality images. Of course, for someone like them who only needs to observe for about 30 minutes, this is not a problem.

"Do you think it's a little too dark?" Qian Yu asked suddenly.

"It's okay......" Gray Yuan Wai shook his head. It's not very bright, but it's barely enough. ”

All the observations would have been fairly well contrasted with the processed images shown in the cinema room, but in fact the images taken with magnification were quite dim – for example, a bright golden sphere with two dark bands around Jupiter at 40x magnification, and at 400x it would have been just a dull white ball with four bands. Chiha's auxiliary unit was able to enhance the overall effect of the image observation by enhancing the contrast at the expense of a little detail accuracy, but there was no way for Ash Hara to do this with the naked eye - fortunately, it didn't seem to affect her observation experience in the eye.

At this moment, G fragments appeared at the edge of the telescope's field of view.

"Here we are." Qian Yu muttered softly.

The reason why Qian Yu deliberately brought Gray Yuan to see the collision of this fragment was not mainly due to the difficulty of observation, but because this fragment was the largest fragment of all the fragments in Sumeklevi, and even more massive than the A fragment that had produced an impressive crater before. Before the collision took place, when Chiba was preparing for the whole process, he had already chosen to observe the debris when it collided with Jupiter, because no matter what would happen to the collision in the end, the G fragment would be the most perfect fragment to interpret all this.

At the same time, the G fragments have quietly submerged behind Jupiter's apparent circle, which also means that the most magnificent scene of the entire Sumeklevy collision is about to occur.

Chiba felt the warmth of his fingertips return, and immediately bent his palms almost without any reason, so that several fingertips fit together with Gray Yuanai's fingertips.

At the same time, a fireball that appeared to be larger than the one created by the collision of the previous A fragments appeared behind Jupiter.

Chiba's hand felt that Gray Yuanai's hand seemed to be reaching out to him, so he flipped his hand over and held it under Gray Yuanai's hand, and the two of them looked at the fireball in the telescope like this.

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

"Of course," the corners of Qianyu's mouth curled slightly. "Why would I bring you here otherwise?"
