How about photographing with a universal telescope?
Telescope is an optical instrument that uses optical devices such as lenses or mirrors to observe distant objects.
The telescope uses the light refracted by the lens or reflected by concave mirror to make it enter the pinhole and converge to image, and then see it through the magnifying eyepiece. Also known as "a thousand-mile mirror". The first function of the telescope is to enlarge the opening angle of distant objects, so that the human eye can see the details with smaller angular distance. The second function of the telescope is to send the light beam collected by the objective lens, which is much thicker than the pupil diameter (up to 8 mm), to the human eye, so that the observer can see dim objects that he could not see before.
