Jupiter image with higher image quality.
I was surprised that a 500mmf4 telephoto lens for cameras could capture such detail.
The presence of the supergiant planet Jupiter is overwhelming compared to other planets, whether you see it or take a picture!
When you look through a telescope, you can feel some kind of huge energy.
The details of Jupiter's surface came out so far with the Goyon telephoto lens
The image above is the image of Jupiter that had the highest image quality among the 39 photographs that were completed this time.
The mole-like shadow on the left side of Jupiter is the shadow of Io, the innermost orbiting part of the Galileo satellite.
Io itself is almost invisible because it is buried under Jupiter, but it is directly to the right of the shadow, just a little to the right of Jupiter's center.
The swirl at the boundary between stripes and bands and the fine shading were captured, resulting in a very impressive image of Jupiter.
The pictures I took before look blurry.
Each time I took a picture and processed it, I made various improvements, leading to this high-quality image of Jupiter.
Last time, I introduced a photograph showing the shadow of the Galilean satellite Europa on Jupiter's surface.
I thought it would be interesting to see the Galilean satellites passing through the surface of Jupiter, so I simulated it with the Stella Navigator 95 and tried to capture the timing.
Since the last time I photographed Jupiter, I had a chance to pass Ganymede and Europa's side of Jupiter at the same time on October 26th, but unfortunately the sky was cloudy.
It was a pity because I could see the Great Red Spot and Io was very close to the right of Jupiter.
The second chance was the next day, October 27th, when the weather was fine, leading to this shoot.
Io is the innermost of the Galilean satellites, and because of its short orbital period, it has the highest chance of overlapping with Jupiter.
The shooting time is from 18:58 to 22:30, shortly after the sun sets.
We continued shooting continuously with a short interval.
Appropriate shooting interval.
The reason is that sometimes the wind blows and clouds cover me, so I can't shoot on time.
I'm aiming for the moment when the wind stops, the vibration of the camera stops, and it becomes clearer.
When the wind blows at the beginning of shooting, I stop shooting, wait for the wind to stop, and shoot again.
The state of the Galileo satellite at the time of shooting
October 27, 2022 at 19:22.
Alignment of the Galileo satellites at the time of shooting
Because Io is on the surface of Jupiter, it cannot be seen in the image, but it is actually visible. The satellites visible on the right are, from left to right, Europa, Ganymede, and Callisto.
All the Galilean satellites are arranged, and the order is exactly from the left to the closest orbit to Jupiter.
Since the exposure is adjusted so that the Galilean satellites can be seen, the bright Jupiter surface is washed out.
With the naked eye, everything from the patterns on Jupiter's surface to the dark moons can be clearly seen.
The dynamic range of the human eye is surprisingly wide compared to that of a camera, so when looking through a telescope, the stripes on Jupiter's surface and the Galilean moons are clearly visible.
This is also the reason why we strongly recommend visual observation with a telescope, as I mentioned in the previous article.
This reasoning is also the reason why managers still prefer to use SLRs for photography.
This is because the single-lens viewfinder not only has an infinite dynamic range, but also an almost infinite frame rate.
In addition, you don't have to worry about battery consumption, so it's easy on the eyes. A high-performance single-lens reflex viewfinder will improve your eyesight.
Mirrorless cameras that stare at the liquid crystal are harsh on the eyes, and if you are not careful, your eyesight will suddenly deteriorate.
The equipment used is the usual Goyon telephoto lens
As usual, I used a Nikon AisED500mmf4.0P with a Vixen NPL6mm eyepiece for magnified photography.
Vixen, tracking with Super Polaris equator, camera used Panasonic GH4.
As usual, I shot a video for about 1 minute and 30 seconds and processed the stacking and Wavelet processing with RegiStax6.
I wonder if I've gotten the hang of how to use RegiStax6.
Many features still don't make sense
The images exported with RegiStax6 are finally processed in Photoshop.
I summarized the whole story of the Jupiter image I took this time in a gif image.
To make it easier to understand the image of Jupiter I took this time, I put it together as a time-lapse movie or a gif image.
You can see the satellite Io moving from left to right while casting shadows on Jupiter's surface.
You can clearly see changes in seeing from the image of Jupiter
When I started shooting, the sun had just set and it was still dimly lit.
The ground surface was warm and the air currents caused the seeing to be unstable and the image was blurry.
After 20:00, the wind subsided and the seeing became better.
Just when I thought it would stabilize, it became unstable again.
the wind blows.
If you look at the change in the image of Jupiter in the gif image, you can see the change in seeing.
Some of the finished sizes of Jupiter have become smaller.
they are scaled.
I think that the stacking process will probably change the size slightly. I noticed this for the first time.
Seeing is the stability of the atmosphere and the visibility of the planet.
Because it was shot at an ultra-high magnification, even the slightest atmospheric turbulence can greatly distort the image.
It's the same as looking at a distant view through the air heated by a bonfire, and if you magnify it with binoculars, the fluctuations will be magnified and you won't be able to see the background clearly.
Jupiter transit of Io
The moon Io passed Jupiter's surface between 19:16 and 21:30, taking about 2 hours and 14 minutes.
At this time of year, the Sun is hitting Jupiter's right side, north-up, and the shadow of its moon Io is projected far to the left.
The shadow projected on Jupiter's huge sphere, and the shadow that appeared to the left of Jupiter is a long and narrow shadow.
During the shooting, I took a wide image of the Galileo satellite arrangement posted above, so some images that show the change in the long and narrow shadow are missing.
Personally, this is the first time I've seen the whole motion of a satellite moving on Jupiter's plane.
There were thin clouds on the way, and it was hidden in the clouds, but it was mostly sunny.
The reason why the image sometimes becomes dark is the effect of thin clouds.
Also, the effect of the wind is the appearance of patchwork.
As much as possible, the parts blurred by the wind are excluded by video editing software, but they come out.
Io's orbital movement seems to move at the same speed as Jupiter's rotation.
Compared to Jupiter's high-speed rotation period of less than 10 hours, the difference in speed is that Io rotates less than once while Jupiter rotates four times.
Since it is 420,000 kilometers from the center of Jupiter, it seems to be about the same speed.
Io's orbital period is 1.769 days (42.5 hours), much faster than the 27 days the moon orbits the Earth.
The orbital radius is larger than the moon, but the orbital period is short due to Jupiter's enormous gravity. Jupiter's escape velocity is 59.5 km/s, which is more than five times faster than Earth's 11.18 km/s.
With its strong gravity, it catches small celestial bodies such as meteorites wandering in space, and it is no wonder that it protects the earth from meteorites.
Like 2001 and 2010 Space Odyssey, if humans go to Jupiter, they will be pulled back to Jupiter again unless they reach a speed of 59.5 km/s or more in order to return to Earth.
Since it is the escape velocity on the surface of Jupiter, the farther away, the slower the escape velocity.
After escaping Jupiter's gravitational field at speed, the spacecraft accelerates further due to the sun's gravity as it approaches the Earth. In order to return to the earth, considerable energy should be required for deceleration. If you actually go to Jupiter and then come back, what kind of orbit will you travel?
Such a future may come, but is it impossible for humans to go near Jupiter because the huge magnetic force and radiation seem to be dangerous?
Impressive image processing capabilities of RegiStax6
From the image projected on the monitor connected to the camera, the appearance of the satellite Io looks so blurry that it can hardly be recognized.
If you look through a telescope, it looks pretty clear.
The image below is the image used for the actual processing.
A material shot in 4K, cropped to the processing size and pixel size.
Such a blurry image morphs into the image of Jupiter shown above.
Dear RegiStax6, I am deeply impressed by the ridiculously advanced processing.
We witnessed something that looked like a UFO during filming!
On a different note, this time I witnessed something that looked like a UFO for the first time in my life!
A flying object moving at super high speed, it felt like an artificial satellite, but its speed was so high that it could not be compared to airplanes or artificial satellites, and it flew straight without making a sound.
The time is 19:12, the direction is the east sky, moving from around 45 degrees to the west sky.
There were many artificial satellites in the sky, and at first I thought it was one of them. The speed was about eight times that of a satellite, and the brightness was about the same as the maximum luminosity of the ISS.
I've been staring at the liquid crystal while shooting Jupiter, and my eyes aren't used to the night sky, so it's not accurate.
It felt like one of the artificial satellites, and it seemed to be orbiting the earth in space, but it was super fast.
As an airplane, as a regular flight, the speed is unimaginable, and it is completely silent.
It could be a drone, but
My wife told me about this flying object while shooting Jupiter.
She was looking at the sky and her eyes were accustomed to the dark sky.
This way of flying, this way of looking is not normal.
Personally, I harvested more than the Jupiter statue this time.
In this three-dimensional space-time, I shared time and time with someone other than human beings for a moment.
That's what happened in the manager's head.
When looking at the night sky from now on, it seems better to keep a camera with a telephoto lens attached so that you can shoot UFOs at any time.
I plan to post it on my blog when I get it.
Yeah, looking at the night sky for ten years, it seems difficult to catch a one-off event.
saturn statue
On the other hand, the image of Saturn, I shifted the pixels and increased the magnification to 200% vertically and horizontally to finish it.
By the way, the top image of Jupiter is magnified to 140% without pixel shift.
The pixel shift is something I tried to imitate the processing that Seamos and CCD Bayer sensors do.
I'm imagining that by processing four pixels, which were originally monochromatic (R-red, G-green, and B-blue), the finished image contains full-color information for each pixel.
The photographed material is the same as the image of Saturn taken on October 7th, and the image of Saturn that is worth seeing is finished by making various adjustments in processing.
The Saturn statue is more beautiful than before
When you take a picture of Saturn, it takes on a bluish-green color, which is different from what you see.
The reason may be that Saturn itself is dark, so I took the picture with a slight underexposure.
However, when you look at Saturn through a telescope, you can't feel the blueness at all, and it looks ocher. The color is so ocher that you can see it even with binoculars with a magnification of about 8x.
Is it an illusion that it actually has a bluish tint and looks ocher?
I don't think so.
This time, I used Photoshop to process the image by applying an orange filter to make it closer to what it looks like.
I finished the image so that it looks closer to the feeling of actually looking through a telescope at Saturn.
The ring is still bluish even though it has been treated to be quite orange.
The ring is pretty blue, I'm sure.
The next time I try to shoot Saturn, I will try adjusting the color temperature and hue during the shooting stage.
I'm thinking of shooting again this season before Saturn still tilts west.
Also, I'm thinking of trying to shoot Jupiter with other telephoto lenses I have, such as Sannippa and Sanyoung.
(It didn't happen. Please forgive me for the next season's challenge.)
Around here for now.
In this example, I think I was able to draw out the performance of Nikon's old manual 500mm lens even more than before. I feel that this lens still has a lot of power left, but I'm thinking of trying various things to achieve even higher image quality.
The motto of the manager is the pursuit of the highest image quality with what I have now! ?
somehow
If you stick to this, you don't need to buy anything.
You haven't contributed to the camera industry at all!
I haven't, but it's eco-friendly! ecological and economical.
Continuing to use what you have is the real eco!
I think it's important to cherish what you can use and keep using it forever.
It is also eco-friendly to buy second-hand goods instead of new ones.
Even though I don't think about such eco.
It's easy on your wallet too.
Don't let such quibbles line up.
