How to use telescope photography

Aim the camera lens at the eyepiece, and the shooting with the optical axis aligned belongs to the eyepiece. This will definitely be able to image, but the effect will be affected to some extent, because the light can only be imaged through the telescope objective (2~3 pieces), the telescope eyepiece (more than 2 pieces) and the camera lens (more than 5 pieces). For example, light attenuation, stray light and aberration increase, image contrast decrease, etc.

The most ideal camera shooting is direct focus shooting, that is, the lens of the camera and the eyepiece of the telescope are removed, and the telescope and the camera are directly connected with a camera interface of 3 1.7mm (or 25.4mm). At this time, the telescope objective lens is directly equivalent to the camera lens, a super telephoto lens. Many planetary photographers take astronomical photos like this, and so do many master astronomical photos.
