Declination (DEC) is similar to the latitude of Earth. It is measured in degrees. Subdivisions for DEC are measured in minutes and seconds of arc. One minute of arc is 60 seconds, and 60 minutes of arc make 1 degree, which is equal to 3,600 seconds of arc. Thus, we can assume how small 1 second of arc is. Declination direction control for polar-aligned astronomical viewing is built on the EQ1 mount of the Sky-Watcher SK8035TAEQ Tabletop Telescope. When the celestial objects to be viewed are faint and difficult to locate, the DEC setting circle can help a polar-aligned telescope locate these objects, whose coordinates are determined from a star chart. Here is how to adjust the DEC of the Sky-Watcher SK8035TAEQ.
