How do I photograph what I see in the telescope?

Direct-focus photography means that the camera is installed on a telescope, without the eyepiece of the telescope or the lens of the camera, and is generally used to shoot nebulae and landscapes.

Eyepiece magnification photography, aim the camera at the optical axis of the eyepiece (the camera can use a lens, and there should be a certain distance between the camera lens and the eyepiece), so the object photographed is very large and is generally used to photograph planets.
