You have the mistaken, yet common, idea that a computerized scope can download its image straight from the scope. It cannot.
A telescope produces a visual, not a digital, image.
You still need a camera mounted on the scope (but there are many kinds of cameras), and a way to capture the images in the camera, or to download the images to a computer.
The easiest way to see planets and Moon is with a simple video camera attached where the eyepiece would normally go. A cable connecting that to a laptop or tablet would show the images as they come in. This can work really well, as 30 frames per second works well on the Moon and planets.

For anything fainter, longer exposures will be necessary, but the basic idea is the same.
