How to use the ordinary lens of planetary camera

Plug-in wide-area and planetary cameras are cameras installed on the Hubble Space Telescope. Ordinary lenses of planetary cameras can be plugged in and used directly. If it's not big enough, add a barlow and the zenith won't be needed. It is used for photography itself and does not need an eyepiece. Just use the star finder to find the target, adjust the parameters, shoot the video directly and then process it with software.
