TWINSTAR demo video
This short demonstration video shows a brief overview of TWINSTAR in action. Covers main AUTOSTAR compatibility, Joystick control, and APP control. See below on this page for further details of all capabilities.
TWINSTAR unit overview
TWINSTAR works alongside your existing Autostar handset - it doesn't replace it. It restores a clear, easy-to-use screen and controls, while adding modern features such as app connectivity and optional joystick control. TWINSTAR connects via the handset's RS-232 port, which is present on all Audiostar and 497 Autostar handsets.
ONESTAR
TWINSTAR stays neat and simple thanks to the ONESTAR interface, bringing power and data together in one cable. Please check the connection image below to confirm compatibility. For best results, handset firmware version 4.3GN is recommended updatable via StarPatch.
Numeric Keys
To keep the handset compact, the numeric keys are replaced with key macros. Considering the text entry is a minimum with the Autostar handset operation, this is a good compromise.
StarPatch
To get the best performance from your ScopeBits products, your Autostar handset should be running the latest firmware. Use your TWINSTAR to act as an interface between your computer and the StarPatch software.
Simply plug your device into your computer using the USB port on each device. Note Scopebits products do not contain handset firmware, they just aim to make it easy to use StartPatch software. Use the guide below to see how to use StarPatch

Check these as they may answer any support questions
No. TWINSTAR is a "twin" to your existing Autostar. If your handset has a broken screen or buttons that are temperamental, TWINSTAR connects to your handset and mimics it, giving you a fresh screen and responsive controls. See this guide.
TWINSTAR is designed to work with compatible Meade Autostar handsets including the popular 497 and Audiostar models. Always check the compatibility information on the product page before purchasing. The most important feature needed is the RS232 socket on your handset. It is the one next to where the handset lead that plugs into the mount goes.
TWINSTAR connects using the ONESTAR products (included). It provides all leads to connect TWINSTAR to your handset and mount. See this guide.
This is a purely personal choice. The support was added because it makes slewing effortless compared to trying to find handset buttons in the dark. Some mounts also allow focus control from the joystick. See this guide.
As the numerical buttons on the 495/497 handset are mainly used for entering speed settings, it was decided that the numerical keys could be accessed via a sub menu. Just click the star icon, use the up and down to select the key and press enter to send it. See this guide.
Yes. TwinStar supports APPSTAR functionality, allowing you to control your telescope through the APPSTAR handset replacement app. See this guide.
Yes. TWINSTAR mirrors the Autostar display and allows you to use the controls just like the original handset, making it easier to operate your telescope when the original display is difficult to read.
No additional power supply is required. TWINSTAR is powered through the telescope handset connection. Ensure if running on batteries that they are fresh. Low batteries can cause the TWINSTAR to not start.
Yes. Firmware updates can be installed through the ScopeBits firmware update tools available on the support website. Updating firmware ensures the latest features and compatibility improvements. Make sure you're using Google Chrome or Microsoft Edge on desktop. Mobile browsers and Safari are not supported for WebUSB/WebSerial updates. See this guide.
Check that all cables are securely connected and that your telescope and Autostar handset are powered on. If the issue continues, restart the telescope and reconnect the device. In some cases the firmware your original handset is running may be out of date. Use the Starpatch feature to load the latest handset firmware, this should enable communication with TWINSTAR. See this guide.

My Autostar keypad had become unreliable and frustrating to use. TWINSTAR completely solved that. It mirrors everything perfectly and gives me confidence when controlling the scope again - bonus with the joystick! A very clever bit of engineering.

I was close to replacing my telescope because the handset screen was failing. TWINSTAR brought it back to life instantly. Setup was simple and the display is crystal clear. I wish I had found this sooner.
Mark D

This is exactly what I needed for my aging Autostar. The mirroring is spot on and there is no lag at all. It feels like a native upgrade rather than an add-on. Very impressed with the build quality too.
Daniel K
Berlin, Germany
I use my telescope regularly and needed something dependable. TWINSTAR has been rock solid. The mirrored display is sharp and easy to read even in the cold. Highly recommended for serious users.
Chloe M

Honestly such a great idea. My handset still works but the screen is dim and hard to read. TWINSTAR makes everything bright and clear again. It feels like a modern upgrade without replacing the original unit. I really like the Joystick more than I tought I would!

A smart and well-executed product. It preserves the original controller while solving its biggest weaknesses. The responsiveness and clarity of the display are excellent. Definitely worth the investment.
