How to Use a Unistellar Telescope

Focusing
For best results it is essential to focus the Unistellar telescope every time the telescope is used. If the temperature changes significantly during an observing session it is optimal to perform an additional focus.

To focus the telescope center the field of view on a star of moderate brightness. Most stars in the Unistellar database, especially those with common names, will be bright enough for this. The telescope's Bahtinov mask is used for focusing. It should be unscrewed from the dust cap and placed on the front end of the telescope. The best focus results are achieved by lowering the gain and/or exposure in the Live View until a small circle can be viewed near the intersecting bright lines. Additionally, it is best to zoom in during Live View to make the view as large as possible (x8).

Focus is achieved by turning the focusing wheel at the back of the telescope. Slowly move the focus wheel until the bright lines symmetrically cross the central bright spot. Atmospheric turbulence will make the bright lines appear move around, so look to make sure that on average the lines cross the central spot.
