Himawari satellite - earth and moon image.
« on: September 15, 2024, 06:11:03 pm »

A friend posted this amazing earth image on Facebook. I commented wondering what kind of lens gave that perspective. He sent links with enough data and specs on that satellite to choke a horse. But I could not find anything about the lenses, if it even has traditional lenses. Anybody know how this was done?

To me it looks like a regular shot from a satelite or spacestation, nothing more, nothing less.

It's a composite. The moon isn't that close to Earth.

Everything the web has about the Himawari satellite covers the megapixels, the scan rates, the transmission speeds, etc., but nothing about the lenses and focal length. Sure, there are a lot of fake composite moon images. But here is a verified real shot, taken at 555mm.

The moon isn't that close to Earth.
Wouldn't you need to know the focal length before drawing that conclusion?

This appears to be approximately a three-quarter moon. The white circle circumscribes the disk of the moon. Question: How could stars be visible in the area indicated? Wouldn't the moon (in shadow) block visibility of the stars beyond?

Possible answers: 1) The moon was added (composited) in post, or 2) the stars were added in post.

Well spotted!

Option 3) these are lights from cities on the Dark Side Of The Moon ...  :)

Thanks, Peano. I think you are on to something. I found it hard to believe that a satellite would have a 400mm to 600mm lens.

Also, the Facebook account of the original poster looks fake too.
