Unistellar Problems: "???" in the App, LED Colors, Blurry Images

Unistellar telescopes create their own Wi-Fi network and are controlled entirely from the Unistellar app. Most problems owners search for are connection drops, blurry stars and Enhanced Vision (live stacking) stopping. These fixes come from Unistellar's help center and cover the Odyssey, Odyssey Pro, eQuinox 2 and eVscope 2.

What the LED color means

"???" in the app, or it won't connect

"???" instead of the telescope status means the app can't talk to the telescope. Unistellar's steps:

1. Turn on Bluetooth and Wi-Fi on your phone, switch on the telescope (LED steady blue or red) and open the latest Unistellar app. The telescope should appear in the list.
2. Connect manually if it doesn't: in your phone's Wi-Fi settings, join eVscope-XXXX or Odyssey-XXXX. No password is needed unless you set one.
3. Turn off mobile data and any VPN. If your phone is also connected to the internet, it can conflict with the telescope's network.
4. Grant permissions: location, local network (iPhone) and network permissions (Android). If unsure, uninstall and reinstall the app to be asked again.
5. Restart the telescope: hold ON/OFF for 2 seconds to switch off, then switch on and wait for a steady LED.
6. Reset the Wi-Fi module: press the ON/OFF button 10 times quickly. The LED blinks purple (then blue) when the reset worked.

Wi-Fi keeps disconnecting

Unistellar says range depends on surroundings: up to about 30 m in open countryside, about 20 m with clear line of sight, 5 m behind walls or glass, and as little as 2 m at crowded events. Its tips:

• Stay within about 10 m and in sight of the telescope; don't observe through a window.
• Forget or switch off your home Wi-Fi so your phone doesn't jump back to it.
• Set your phone's auto-lock to at least 2 minutes and don't switch to other apps mid-session.
• Make sure you are the operator, not a watcher, in the User tab; only the operator can control the telescope.

Images won't save

Unistellar's app needs full photo library access to save images. If you see a save error, go to your phone's settings, open the Unistellar app's permissions and allow full access to Photos, plus location, Bluetooth and local network.

Blurry stars

Odyssey and Odyssey Pro: Unistellar recommends letting the telescope cool to the outside temperature for at least 30 minutes, then running the orientation process in the app, which also refocuses. Repeat orientation if the first result isn't sharp, and re-orient each time you change target.

eQuinox 2 and eVscope 2: turn the focus wheel at the back of the telescope until stars become points. The Bahtinov mask supplied in the cap helps fine-tune focus.

See our blurry image checklist for causes that apply to every smart telescope.

"Enhanced Vision Disrupted"

Enhanced Vision is Unistellar's live stacking. Unistellar lists these causes for it stopping: thin cloud, smoke or haze; a temporary firmware hiccup (switch off and on); Wi-Fi disconnections; dew or frost on the mirror or sensor; a dirty mirror; small vibrations; and a tripod that isn't level or tight.

The specific messages:

• "Vibration detected" or "Too bright": one frame was rejected (a bump, or someone's phone flash). Stacking continues.
• "Important shock detected": re-level the bubble and redo Focus & Track.
• "Too close to zenith": Unistellar advises staying between 20° and 80° altitude.
• "Tracking issue detected": check focus and collimation.

Unistellar stresses checking that every tripod clamp is tight: a loose clamp lets the telescope sag slowly, which shifts the level without you noticing. For dew, see our dew guide.

When to contact Unistellar

For a white LED, repeated failures or physical damage, contact Unistellar support with the telescope model, serial number, LED color (with a photo), your phone model and OS version, and the steps you've tried. The warranty is 2 years from delivery and 6 months on the battery; Unistellar says opening or modifying the telescope voids it.
