![]() However, if you are using a heavy eyepiece or a larger smartphone, you may need to add more tension so that the telescope remains still when not touched. Under most circumstances, you won’t need to add much tension. Turn the knob to add enough tension to provide a smooth up-and-down motion. (NOTE: the other knob on the opposite side does not function for adjusting altitude tension.) ![]() You can adjust the tension along the altitude axis by turning the knob located on the same side as the telescope’s focuser-the altitude tensioning knob (Figure 4).įigure 4: The tension of the altitude motion can be adjusted with the altitude tensioning knob. Using thisknob also prevents heat from your hand from entering the optical path, which can temporarily distort the view.įigure 3: The panning knob provides an excellent place for your fingers to grasp when pointing the telescope. The panning knob at the front of the telescope tube provides a convenient place to grasp the tube for pointing (Figure 3). Simply move the telescope tube up and down and left-to-right until the telescope is pointed toward the desired object and the object appears in the telescope’s eyepiece. ![]() Figure 2: The StarSense Explorer Dobsonians have two axes of motion: altitude (up-and-down) and azimuth (left-to-right).
