Yes. Except it is like looking through a telescope from the place being observed with it.
Not at all.
Astral travel or astral projection/remote viewing is the supposed ability to mentally/spiritually travel outside the body and observe remote objects anywhere.
Looking through a telescope is the simple act of physically looking through a device that magnifies visible remote objects.
LOL, Astral travelling is when you are asleep and you leave your body and go flying around, my friend does it all the time, I do it sometimes but hate the falling feeling when I’m coming back into my body, it wakes me up and scares me lol 🙂
An out of body experience is how it’s usually referred to and I suppose you are usually looking down whilst astral travelling not up 🙂
