Smart telescopes were introduced to the consumer market in the 2010s. They are self contained astronomical imaging devices that combine a small (50mm to 114mm objective) telescope and GoTo technology with pre-packaged software designed for astrophotography of deep-sky objects.
A key modification of the original design is the hinged suspension of the drive rod, which avoids binding, as well as a central tripod mount that can be moved along the supporting truss tubes to better balance for lighter or heavier loads according to their orientation. For proper polar alignment, a 3-way tripod or azimuth wedge is required ...
The equatorial axis of the mount is often equipped with a motorized "clock drive", that rotates that axis one revolution every 23 hours and 56 minutes in exact sync with the apparent diurnal motion of the sky. [3] They may also be equipped with setting circles to allow for the location of objects by their celestial coordinates.

The ETX started out as a 90 mm (3-1/2") Maksutov Cassegrain telescope (first produced in 1996) and took advantage of high volume mass production and simplified optical and parts construction to open a new market for a cheap alternative to the very expensive Questar 3-1/2 Maksutov Cassegrain [1] [2] The ETX "line" has been expanded to 105 mm, and 125 mm Maksutov Cassegrains and achromatic ...
