Does Stella require internet access to work?

Don’t worry, you don’t need internet for Stella to work properly! Unlike Bluetooth, Stella requires no pairing and no special drivers. Supporting a DHCP server or client, Stella can enable your telescope to be remotely controlled. All you need is a Wi-Fi enabled device like an iPhone, iPad, iPod Touch or Android device.


How does Stella work?

Stella creates its own 802.11 wireless network. By default, this is an open wireless network called "Stella", but you can rename and secure as you wish. You join this network from any of your qualified devices and just like that... you're ready to use Stella! As long as your device gets its IP address by DHCP, no additional network configuration is required.


Battery Life

Stella uses a rechargeable Lithium-Ion battery. It has a typical battery life of 4-8 hours under continuous use and offers a “power-saving mode” to aid in increased battery life. Stella can also be powered from an external source, like USB ports or wall socket. Cables for both AC power (120V, 60Hz) and USB to micro-USB are included.


Stella Apps, Software and Firmware

To complete your Stella experience, you'll download and purchase our telescope control application, StellaAccess onto your iPhone, iPad, or iPod Touch or Android device. The Stella Wi-Fi adapter works seamlessly with StellaAccess app as well as the SkySafari software. Firmware is upgradable via computer. Note: You'll need the mobile application, StellaAccess to use the Wi-Fi adapter.


Does the mobile app, StellaAccess, come free with Stella?

No, purchasing Stella Wi-Fi adapter does not include the mobile application, StellaAccess. StellaAccess is available for purchase from the Google Play Store or Apple iTunes Store.


Compatible Telescopes

Stella can wirelessly enable almost any telescope with a standard USB or RS-232 serial interface. Models that have been tested and are known to work with Stella include:

  • Meade LX200 Classic and GPS

  • Meade LX400 ACF

  • Meade LX600 / LX850

Some Meade ETX models (60/80) ship with the Autostar #494 controller. To make Stella work with these scopes, you need to replace the #494 Autostar controller (which does not have a serial port) with the AudioStar (which does). Contact Meade to upgrade your controller.

Fully-featured planetarium application.

With over 2.5 million objects including stars, deep-sky objects, asteroids, comets, and satellites, StellaAccess is your road map to the night sky. Simulate the sky from any location on Earth, past or present. Simulate transits, eclipses, and other events with time controls.

StellaAccess can also help you identify objects in the night sky by holding up your phone or tablet. With Compass and Gyro support, the sky chart will follow your motion as you move your phone around, giving you a new way to look at the night sky.

Other notable features include iridium flare notifications, ISS tracking, Orbit Mode to simulate views from other worlds, object descriptions with color astrophotos, observing session planning, Night Vision Mode, and “Tonight at a Glance”, giving you a tour of the best objects in the night sky based on your time and location. Gyro support, the sky chart will follow your motion as you move your phone around, giving you a new way to look at the night sky.

Wireless Telescope Control

StellaAccess includes state of the art mobile telescope control. With your telescope connected to the Stella Wi-Fi adapter, StellaAccess allows you to control your Go-To telescope remotely.

Once paired with your telescope, you can move your telescope through StellaAccess with the directional arrows. You can also select objects above the horizon and use StellaAccess’s GoTo feature to have your telescope slew to the object selected.



Using StellaAccess as a Telescope Controller

To use StellaAccess as a telescope controller, your telescope must be connected to the Stella Wi-Fi adapter and your mobile device must be connected to the Stella Wi-Fi network. Your telescope must complete any necessary alignment procedures before connecting to StellaAccess. Reference your telescope manual for detains on your scope’s alignment process. Before tapping the “Connect” button, review the “Settings” page to ensure you have the correct settings.

Under “Telescope”, choose “Setup” and be sure you have the following settings:

  • Select the telescope in use under Scope Type.

  • Select the mount in use under Mount Type.

  • Stella Name set to “Stella” or “10.0.0.1”.

  • Port Number set to “4030”.

Once you have the correct settings in place, you are now ready to connect to your telescope. StellaAccess remembers the telescope’s alignment until you quit the app, so you should not have to realign if you disconnect (or are accidently disconnected). Once connected, you can control your telescope with the directional arrows, or use the GoTo feature to point at a selected object.

You can re-align the scope and the software anytime there is a discrepancy between the two with the “Align” feature. This synchronizes the scope to coordinates of the selected object. The bullseye indicated in the sky chart shows where the telescope thinks it is pointing. If that appears incorrect, the scope and the software must be aligned.

To do so:

  • Physically center the scope on a real object in the sky.

  • Select that object in the sky chart to make it the current target object.

  • Tap the Align button.

When you are finished with your session, tap “Disconnect” to end your telescope control session.
