It is worth mentioning that astronomic photography or astrophotography meant a huge step forward in the field in the eighteenth century with the use of daguerreotypes and has made possible a multitude of findings ever since until this day, now mainly thanks to the use of digital photography, a technology available to anyone nowadays that, when used following the large exposure method and subsequently processed, allows a gradual observation of celestial objects, as they are slowly captured due to the accumulation of photons in a photographic sensor during the time the camera remains open, as opposed to how they appear through human vision, incapable of generating such light accumulation. This technology opens the door to discover a part of nature such as the firmament, which would otherwise be hard to observe.

Manually steerable equatorial mounts (image 1) have been used by amateur astrophotographers for decades, but technology nowadays allows a full automation of the mounts for little money and thus get rid of the need to guide the camera.

It is worth clarifying that limitations may arise. Lenses with a focal length over 100mm are likely to be imprecise when lining up with the celestial pole. Classical 50mm lenses are more recommended, specially for first tryers, and are likelier to provide results that are more satisfactory, due to their luminosity.

On of our purposes is to promote the joy and fondness for astrophotography and astronomical observation by giving precise and detailed instructions so that anyone that may be interested can build a mount.
