They specified at least one planet in our solar system.
Most likely, they will start close in and then focus further and further out.
I am thinking Jupiter or Saturn, maybe Proxima Centauri (the closest star), maybe a globular cluster outside the Milky Way, Andromeda (the closest large galaxy), the North Star, Sirius (the brightest star), a couple constellations and nebula, a comet maybe?
Just really photogenic things that most people have seen or heard about.
They need to fine tune each telescope segment so they all focus on and perfectly reflect the same image.
Whew!
That turned into a long post - did not realize I knew that much about astronomy.
Old guy - way too much free time!
The hubbele imaged the Cat’s Eye nebula years ago. They ended up doing 3 or 4 separate images of it over time, and someone took the 3 images and made an animated gif of it. It’s kinda cool to actually be able to watch it expand over time. I really wish they could commit to a shot every year.
