This time, I took a picture of the International Space Station on which Astronaut Maezawa, a businessman, was on board, so I will take up that matter.
Shooting the ISS for the first time in a while
I tried to shoot the ISS International Space Station, a blog I wrote earlier about ISS! The number of visits has increased recently.
I wonder what? When I looked into the Japanese news for the first time in a while, I learned that Japanese commercialization was on the International Space Station. This is December 10th.
So I decided to shoot the ISS for the first time in a while.
Since the last blog update, I've come up with the idea of shooting the ISS several times, but every time I see it one week or two weeks later.
The timing wasn't quite right, I didn't have much passion, and when I realized it, the days I could see it had passed.
I haven't taken a picture since the last blog post about the ISS, and I've reached the present.
By the way, will the ISS pass over Nairobi at a good timing while Astronaut Maezawa and Astronaut Hirano are on board this time?
As usual, when I checked the next best time to see it with the smartphone app ISS Detector, I found that it would pass over Nairobi at around 19:30 on December 11th, the next day.
Good timing! I'm sure the usual behavior was good. What kind of?
Take a picture from God! It may be a message.
From the northwestern sky to the southeastern sky, passing directly above Nairobi, the luminous intensity is minus 4.5 mag. Great conditions!
The sky was fine on the day, and about 30 minutes before the passage over the ISS, I went up to the roof of the apartment, prepared for shooting, and waited for the passage of the ISS.
Following the previous shooting with Panasonic's GH4, I used Nikon's D850 as the shooting equipment.
As with the last time, the lens is Nikon's manual 500mm f4P, and the combined focal length using two teleconverters x2 and x1.4 is 1400mm.
The exposure was adjusted to the moon shining near the zenith, and the focus was adjusted to Jupiter.
The focal length of a combination of two teleconverters on Goyon is 1400mm, and it is impossible to hold it, so I used a tripod.
I used Gitzo's 3 type 4 steps, aluminum legs, and the pan head Zahard FSB4, which is active in video shooting.
And the photo below was taken.
It is taken without compositing, and some processing is done to make it easier to see.
Since it is small, it outputs at 200% pixels.
ISS passing over Nairobi
Shooting date: December 11, 2021, 19:36:23
Location: Kenya, Nairobi, rooftop of home
Astronaut Yusaku Maezawa and Astronaut Yozo Hirano are on board in the space station in the photo.
The world of romance, which does not change at all as a photograph even though it is appearing.
In any case, I was able to shoot at a good timing.
The living space where the astronauts stay is the upper part of the elongated cylinder that extends up and down in the middle.
Perhaps Japanese astronauts are in this habitation module.
Following on from Astronaut Noguchi, who was on board the last time he was filmed, Japanese people are on board this time as well.
As a Japanese, I was happy.
Even though it is a universe, the distance from the ground when passing over the sky is ridiculous 400 km, which is quite close.
You cannot reach the sea of Mombasa from Nairobi (500 km).
It seems that the sky above 100 km is decided by the universe.
Is the meaning completely different between horizontal and vertical?
However, that is because of gravity, and the distance in three-dimensional space does not change to 400 kilometers.
Do you see the land of Kenya from the commercialization, astronauts, and the sky?
Do you have a busy time at the space station and do you have time to do that?
He watched the ISS fly over with his family, three children and his wife.
Or rather, the caretaker was crazy about shooting, and his wife was talking to the caretaker while passing over, but she couldn't hear anything.
Manager, if you are absorbed in shooting, you may not be able to hear the surrounding sounds.
It's dangerous.
So when I finished shooting, her wife was in a bad mood.
After shooting,

The resolution of this photo is inferior to that of the previous one.
The pixel pitch (4.35μ) of the imaging pixels of the Nikon D850 used this time is slightly larger than the previous Panasonic GH4 (3.75μ), so the size is smaller and the image resolution is inferior.
In addition, while I stopped down one step firmly last time, this time I stopped down only about 1/3 step to get more light in order to get a faster shutter speed.
It's not like the old-fashioned lenses, the latest crisp lenses, and super sharp lenses.
That's probably the reason why it's voyating.
Next time, let's squeeze it properly.
Furthermore, two teleconverters are stacked.
I thought I'd use another double teleconverter to make it a triple teleconverter, but the shutter speed would be stricter, so I shot with a double teleconverter.
I felt that it was important to shoot such distant and small objects and to have a small pixel pitch.
It is suitable for small subjects because it has a small pixel pitch and does not need to be optically magnified.
If you take a closer look at the photos of this ISS
The photo above is blurry, but you can see the habitation module (upper right) and the experimental module (lower left) that penetrate the center up and down.
And solar panels connected to the left and right by trusses.
It can also be seen that the angles of the left and right solar panels are slightly different.
The white shining part on the left of the center is the heat sink.
At the bottom of the cylinder, at the tip of the cylinder on the left, which branches to the left and right from the experimental module, is the module in charge of Japan, Kibo.
In the upper right, beyond the tip of the habitation module, Soyuz is used for round trips to and from the ground, as if it were there or not.
Can you see it? Imagine and delusion, and you can see it gradually.
Isn't it not possible to enter while it is in the picture?
It's a so-called delusional world where you can see things that you can't see because you compare them with the very clear pictures of the ISS taken in outer space.
In a nutshell, the image will swell.
The impression changes greatly depending on the difference in language.
By the way, the photo below was taken last time.
This is a combination of several frames that are well-captured in a video, combined, and stacked.
The resolution is clearly higher than the photo above and it looks clear.
Taken on March 12, 2021
As a response, I feel that the performance of the lens and sensor should be able to take higher quality pictures.
In the future, I will try again with the aim of achieving even higher image quality on ISS photographs.
By the way, what time will it be?
If you can take a good picture, I will post it on my blog.
The world of photography, where artificial satellites that are so far away and almost invisible to the naked eye can be seen as photographs.
I felt that it was quite a second thing.

Until the end Thank you for reading.
