How this satellite was photographed, the crater is clear at a glance.

Hello, landlord. Look at the size of the moon in the picture. It doesn't look like it was shot with a 70-200mm lens, but it may have a larger focal length.

Or take advantage of the advantages of 1.6 times that of Canon APS-C camera, perhaps you can get a larger focal length and shoot the moon of the size in the picture.

For celestial photography like the moon, if it is close-up, it is necessary to use a telephoto lens; Secondly, when shooting, you can use real-time shooting to better focus. If you use the viewfinder, the focusing speed will be very fast, but it is easy to make the subject out of focus. Real-time shooting can confirm the focus position with the advantage of magnification; Third, the focal length should be appropriate. If the moon occupies a large area in the photo, autofocus is fine. If the camera can't focus automatically, manually set it to infinity (a little further back) so that the moon can focus accurately; Fourth, the exposure should be accurate and not overexposed, otherwise the moon will become a bright disk, and the shutter speed should not exceed110s (the moon is much brighter than you think, and only a high-speed shutter of 1/300s is needed on a clear night). The aperture of the moon is F5.6, and the full moon is F 1 1 (the experience of photographers from various countries).

If you want a bigger moon, you need a lens over 600mm and even an astronomical telescope. But the shooting techniques are similar.
