Best Telescope Wi-Fi Adapters - Reviews

1. Celestron - SkyPortal WiFi Module

The Celestron Skyportal is a WiFi module that can be used to align your Celestron telescope. 

For the product to work, all you have to do is connect the Celestron Skyportal Wifi Module in the AUX or Hand Control port of your telescope, and then connect your device to the module via Wi-Fi. 

The Celestron astronomy software (Sky Portal app) will turn your module into a hands-free control center to work with your scope. 

You can manage your scope either with your iOS or Android device

As SkyPortal Wifi Module slews your telescope to an object, you can listen to hundreds of included audio descriptions on your device, which explain the history, mythology, and key features of the most popular celestial objects.

The Celestron SkyPortal module is a very simple device with only a few buttons. 

On the left side, you have one small hole where you can find the RESET button. 

On the right side, there are one switch and indicator lights. 

The switch button is for switching between Direct Connect Mode and Access Point Mode(WLAN). The three indicator lights are for Mode, Connection Status, and Activity.

Possibly one of the greatest features of the Celestron Skyportal Wifi Module is that it is incredibly easy to set up. 

All you have to do is plug it into your telescope and use the Android or iOS app with WiFi to work with your scope hands-free.

The unit works only with telescopes & mounts made by Celestron, including:

  • Advanced VX -CGX-L
  • Astro Fi -CPC, CPC DX
  • CG-5 (with CG-5 Aux. splitter) -NexStar Evolution
  • CGE -NexStar GT (2015 models and newer with Aux. splitter)
  • CGE Pro -NexStar SE Series
  • CGEM II -NexStar SLT
  • CGEM, CGEM DX -SkyProdigy
  • CGX -LCM

The Celestron Skyportal Wifi Module is a simple telescope accessory that does not require any other accessories to function (no batteries, no external charges). However, you will need to download the SkyPortal app for your product to work. 

2. Orion SynScan Wi-Fi Adapter

The Orion SynScan Wi-Fi Adapter can wirelessly control any Orion GoTo telescope or mount that operates using the SynScan handset via your iOS or Android smartphone or tablet.

All you need is the free app and the Orion SynScan Wi-Fi Adapter.

The thumb-sized SynScan Wi-Fi Adapter plugs into the hand controller port of your mount with one of the two short cables provided. 

For the Atlas EQ-G just use the hand controller cable that came with the mount. After downloading the free SynScan Pro app from the App Store (for iOS) or Google Play (for Android) onto your device, you join the SynScan Wi-Fi network on your phone or tablet and hit “Connect” on the app’s opening screen. That’s it! You’re now ready to control your Orion GoTo telescope with your mobile device.

The SynScan Wi-Fi Adapter creates its own Wi-Fi network, so you don’t need internet access or Wi-Fi hotspots to use it in the field. 

The SynScan Pro app’s user-friendly touchscreen menus are neatly organized and offer easy navigation. 

Furthermore, the current time and location are synced from your phone, making star alignment faster.

The SynScan Wi-Fi Adapter is compatible with all Orion GoTo mounts and GoTo telescopes, including:

  • StarSeeker
  • SkyQuest GoTo Dobsonians
  • SkyView Pro GoTo
  • Sirius and Atlas EQ-G
  • Sirius Pro and Atlas Pro AZ/EQ-G
  • HDX110 EQ-G

The SynScan Pro app is not a planetarium program but simply replaces the SynScan hand controller.


Taking into consideration all of the aspects, we can conclude that the Celestron – SkyPortal WiFi Module is the best telescope wi-fi adapter currently available in the market. 

It is a pretty simple telescope accessory that allows you to observe and learn about celestial objects hands-free.

You will get more control over the telescope. You don’t have to touch your telescope anymore causing vibrations like with the hand controller.
