The NEEWER LS-T22 1.25" Electronic Telescope Eyepiece is designed to make digital stargazing more accessible and user-friendly than ever. Built to fit any telescope with a standard 1.25-inch focuser, this compact device replaces the traditional eyepiece with a digital imaging system. Instead of squinting through glass, observers get a live 1080p image streamed directly to their phone or tablet through a wireless connection. Its built-in low-light CMOS sensor captures clear views of the Moon, planets, and bright deep-sky objects. You simply power it on, connect to the eyepiece’s Wi-Fi hotspot, and launch the NEEWER app, from there, you can view, record, and save what your telescope sees, right on your device.

Ease of use is one of the LS-T22’s biggest selling points. There's no need for cables, adapters, or computers. The entire experience runs wirelessly, powered by a built-in rechargeable battery with about 2.5 hours of operating time. Once it's inserted into the telescope, you handle everything else from the app, including live preview, brightness adjustments, and capturing photos or videos. The sensor is optimized for lunar and planetary imaging, offering excellent contrast and clarity for the Moon's surface and planets like Jupiter or Saturn. While it isn't designed for deep-sky astrophotography, it handles bright objects well enough to satisfy beginners or casual observers. For public demonstrations, outreach, or educational purposes, this eyepiece shines, literally projecting the cosmos onto a screen for everyone to enjoy.

Beyond the optics and electronics, the LS-T22 is also a well-thought-out piece of gear from a design standpoint. It weighs just 4.9 ounces, making it easy to transport and mount without throwing off telescope balance. The body combines durable ABS plastic with metal components for a lightweight yet sturdy feel. It comes with a USB-C charging cable and dust cap, though there’s no included case. While it lacks advanced features like gain or exposure control, its simplicity is the point. This is a device made for beginners, students, and hobbyists who want to see the Moon in HD on their phone or share Saturn’s rings on social media with a single tap. With a current price around $100, it’s a compelling alternative to more complex and expensive imaging setups.
