Focusing To focus, if you have a StarSeeker IV Newtonian reflector or refractor telescope, simply turn either of the two focus wheels on the focuser until the image looks sharp. For the Maksutov- Cassegrain models, the focus knob resides to the right of the visual back, or accessory adapter.

Well collimated optics are critical for achieving the sharpest possible images with your telescope. Precise colli- mation of StarSeeker IV telescopes is done at the factory, and for the StarSeeker IV refractor and Maksutov-Cassegrains, it should never need any further adjustment. For reflectors, on the other hand, occasional collimation of the mirrors may be necessary.
The SynScan menu tree is a useful reference to the menus that the con- troller will display when connected to the StarSeeker IV mount. In this manual only the most important func- tions are explained in detail to help you start observing with your StarSeeker telescope.
