Telonixium WiFi eyepiece camera (V13) review
A Wi-Fi electronic eyepiece with a 1.5-inch IPS screen, 1080p video and 2 MP photos, a 1000 mAh battery for up to 3 hours, a 64 GB card and a clamp for 28 to 50 mm eyepieces.
This is not a camera that replaces an eyepiece. It clamps over one, on any instrument with an eyepiece of 28 to 50 mm, and records what that eyepiece shows: telescopes, binoculars, monoculars, even microscopes.
Published runtime and storage
A 1000 mAh battery for up to 3 hours, USB-rechargeable and usable while charging. A 64 GB card is included, with support for 256 GB.
Screen and Wi-Fi
A 1.5-inch IPS screen shows the view; a phone app over Wi-Fi shows it remotely, on two devices, up to 49 ft away. Video is 1080p, photos 2 MP.
What it is for
Sharing the Moon with a group, filming wildlife through binoculars, recording a session. For stacked planetary images, a camera like the SV105 does more.
Against the larger Telonixium
The 4K model has a bigger screen and battery and a wider clamp, at twice the price.

What observers ask about this one
How is it different from a planetary camera?
A planetary camera replaces the eyepiece and records the telescope's own image. This clamps over an eyepiece and films what the eyepiece shows, like a phone held to it, with its own screen and battery.
How long does it run?
The listing states up to 3 hours from the 1000 mAh battery, and it can run while charging from a power bank.
What does it fit?
Eyepieces and binocular eyecups from 28 to 50 mm in outer diameter.
