This summer, on July 31st, Mars will be approaching for the first time in a while, and it will be the best time to see the outer planets together with Jupiter and Saturn.
I will report on the challenge of shooting the planet at high magnification.
It is standard to use an astronomical telescope to shoot planets, but since there is nothing that can be used, I tried shooting with the equipment I currently have.
It was taken with a telephoto lens instead of a telescope.
The equipment used is
Nikon's 300mm f2.8 telephoto lens instead of an astronomical telescope,
Vixen PL10mm eyepieces to magnify the planet,
The camera is Panasonic's DMC-GH4.
A long time ago, when I was a student, I had a magnifying image adapter that I used to shoot planets and the moon with a film camera, so I decided to attach it to the back of a telephoto lens for shooting.
The Nikon telephoto lens used is used as a telescope with an aperture (D) of 107 mm and a focal length of (f) 300 mm.
The focal length is too short to shoot a planet, but I'm looking forward to seeing how much it can be captured with a high-performance photographic lens.
As for the gantry, I overloaded the Sky Memo T made by Kenko Kinner Co., Ltd. and the portable equatorial system, but I decided to use it.
I prepared for the shooting and the weather was fine, but it wasn't clear, and on May 15th, when it cleared up after a long time, I went to a nearby park and tried to shoot the planet.

High-magnification camera mounted on a free platform, a difficult technique to see a small planet,
Finally, I succeeded in fixing Venus in the field of view.
Work while looking up in a crouched posture, stiff shoulders!
When calculating the focal length, the full size is equivalent to 3,600 mm, and since it is Four Thirds, the angle of view is about 7,200 mm.
You can see the narrow field of view.
A long time ago, when I was shooting on film, I used to release the shutter aiming for the moment when the atmosphere was stable.
In order to prevent the shutter from vibrating, I used to use a black fan in front of the lens instead of the shutter.
Now in the digital age, it's very easy!
Take a video, capture it later as a photo from the video, and extract and synthesize only a stable image.
It's called stacking.
The free app (Registax) will automatically do the compositing work that seems to take time.
Such a great app is also free! You can easily look up such information online!
I think it's a great time.
The manager also knew it for the first time by searching on the net this time.
It doesn't cost real money.
I think it's a very good thing, but I think it's going to be a society where it's difficult to make money.
The sky was very bad, and Venus, which I saw after a long time, was fluttering with Gunyogunyo.
After image processing on Venus, the image was finished as it was.

By performing image processing, it is possible to confirm the lack of Venus as it is.
Now that Venus is escaping from the earth, when viewed from the earth, Venus gradually approaches the sun, and it becomes darker and harder to see.
Venus, which orbits the inside of the earth, moves faster than the earth.
After a while, it will appear as a morning star.
When Venus is low in the western sky, Jupiter is in the eastern sky.
The sinking Venus and the rising Jupiter.
Focused on Jupiter.
Again, stiff shoulder work,
Finally, with a view to Jupiter, I started shooting.
It was reflected as it was, but Jupiter is still low in the sky and seeing is bad, so I decided to shoot again.
The picture of Jupiter above was taken the next day.
When I checked the sky condition from the balcony of my house to go to the park to shoot Jupiter again,
Nothing happened, Jupiter was completely visible from the balcony.
Taken from the balcony of the house.
The sky and seeing were quite good compared to the first day, and a little bit of stripes and bands appeared.
To be honest, I was surprised that Dietel would come out so far with a 300mm telephoto lens.
The telephoto lens is excellent.
Is the darkened part of the stripe a Great Red Spot?
The Great Red Spot, which has changed its shape but has not disappeared since human beings were first confirmed with a telescope.
A huge typhoon that completely covers the earth, an unimaginable storm may be blowing.
Next time, I will try to shoot Mars and Saturn.
Saturn is far and dark, so will it be captured on the GH4, which has a shutter speed of only 1 second?
