Thank you for purchasing StellarMate! Please follow this guide before you starting using your StellarMate Gadget.

Stellarmate allows the user to control/access their scope and camera from one of 4 kinds of devices: phone, tablet, laptop, or desktop. In each case both the user device and Stellarmate need to be connected to the same network. If you have a wired network available, both Stellarmate and your laptop/desktop would be connected to the same wired network. For phones and tablets, WiFi is used (and can be for laptop/desktop as well). For WiFi, either you have your own WiFi (in range for both your device and Stellarmate), or you both use the WiFi hot spot provided by Stellarmate (which shows as Stellarmate).

Once connected, you use an app on your device for control/access. For phones and tablets this is usually the Stellarmate App. For laptop and desktop this is the KStars application. You define an equipment profile (that describes your connected scope gear) and connect to that for control.

After connection is established, you can do things like move the scope, enable tracking, GOTO specific objects in the sky, view camera images, take pictures of capture video, etc. The range of options here is extensive based on what gear you have available at the scope end.
