Sky Engineering Sky Commander XP4 Flash Computer Module

What is the Sky Commander?

The Sky Commander is a small self-contained computer designed for the specific purpose of locating and identifying celestial objects with a telescope.

How Does it Work?

The computer reads the position of the telescope with the use of two optical encoder modules. The encoders are attached mechanically to the telescope axes in such a way that the encoder shaft turns as the telescope is turned. At the beginning of an observing session, the user initializes the computer by pointing the telescope at two different stars. By sensing the change in position between the two stars, the computer is able to fix on the orientation of both telescope and sky.

How do I point the telescope to an object?

A six-button keypad and LCD display from the easy operator interface. First, you select a catalog, e.g. Messier, NGC or Planet. Then you enter the catalog number (four digits). Arrow buttons are used for this purpose. Pressing the ENTER button makes the object current. The user moves the telescope while watching the LCD. As the scope moves closer to the target object, the display digits roll down to zero in AZ and EL. Arrows are displayed to indicate direction.

The Sky Commander XP4 Flash was designed especially for those amateurs who would like to be able to locate and observe celestial objects fast and easily. With the aid of the Sky Commander XP4, more time can be spent at the eyepiece and less time at the finder scope and sky atlas. Objects are located by entering their catalog number using push buttons. A liquid crystal display shows you the scope's position and lets you 'zero in' to objects. With a little practice, you can locate even hard to find objects in seconds.

The Sky Commander XP4 is based on the original Sky Commander DSC (digital setting circles) design but with the following important hardware upgrades:

4 times the internal memory space  512kB vs 128kB, allowing room for many more objects to be stored, up to approximately 30,000.
