The core appeal of the SmartEye is that it reveals deep-sky objects that would otherwise remain invisible to the human eye through conventional optics, offering live-stacked, real-time views enhanced by modern imaging technology.

Unlike self-contained smart telescopes that lock users into proprietary hardware, the SmartEye builds on the gear an astronomer already owns. It can be attached to any telescope equipped with tracking capabilities, including GoTo mounts, and integrates seamlessly into different observing setups. This flexibility sets the SmartEye apart from other smart telescope products by providing advanced digital observing without forcing users to abandon or replace their existing equipment.

The device arrives well-packaged with a range of accessories. Inside the box is the SmartEye itself, protected by caps on both the sensor and eyepiece ends. A high-quality USB-C power cable and a 12V DC to USB-C power adapter are included, providing versatile power options for different setups. The SmartEye features an M54 thread at the front, allowing the included 2-inch nosepiece to be screwed in. That nosepiece accepts 2-inch filters, essential for optimal image quality, particularly because the SmartEye’s sensor lacks an internal IR-cut filter. Users relying on 1.25-inch eyepieces or filters can easily adapt the SmartEye with a simple step-down adapter.

The device’s physical features are intuitive and practical. The rear section houses the eyepiece lens, behind which lies the OLED screen displaying live-stacked images. A diopter adjustment ring allows users to fine-tune the focus based on their eyesight, much like with binoculars or DSLR cameras. Control of the system is handled through the "astro crown," a rotating knob reminiscent of the Apple Watch’s digital crown, which enables easy menu navigation and settings adjustments. Other features include a USB-C port for power and firmware updates, a microSD card slot for saving images, and a Wi-Fi antenna for wireless connectivity. An ST4 guiding port is present as well, although external guiding is not yet available in the current software version.

The SmartEye offers three main operating modes to suit different users and scenarios. The first is standalone mode, which is perhaps the most straightforward and approachable. Users simply attach the SmartEye to a telescope with tracking capabilities, power it on, and enjoy live-stacked images through the eyepiece, no apps, cables, or computers required. After performing standard alignment procedures with the telescope mount, users insert the SmartEye, connect the power, and follow the on-screen setup prompts using the astro crown. A short dark-frame calibration process helps optimize image quality by reducing noise. Once in live view mode, the SmartEye displays stars and deep-sky objects in real time, allowing for precise focus adjustments before initiating live stacking.

Live stacking begins with a series of short exposures, typically around 10 seconds each. The device automatically aligns and stacks these frames internally, enhancing the image progressively as more frames accumulate. Initially, images appear faint and monochromatic, but over time, color and detail emerge as the signal-to-noise ratio improves. The process feels interactive and immersive, giving users the sense that they are watching the image form in real time, similar to collecting photons through a traditional eyepiece but with vastly enhanced visibility. Brightness and contrast adjustments can be made at any point using the astro crown, further tailoring the experience.

Standalone mode is ideal for casual observing, public outreach events, or situations where simplicity and minimal setup are desired. It allows for an engaging observing session without the need for additional devices or complicated software, making astronomy more accessible to beginners or those seeking an intuitive, hands-on experience.

The second operating mode takes the SmartEye’s functionality further by integrating it with SkySafari Plus or Pro, a popular mobile app for telescope control. By connecting the SmartEye and a compatible GoTo mount to the same Wi-Fi network, users gain full control over telescope alignment, plate solving, and object slewing directly from their phone or tablet. This effectively transforms any traditional telescope setup into a fully integrated smart telescope.

The setup process involves connecting to the SmartEye’s Wi-Fi network, which the device broadcasts upon startup. Once connected, SkySafari automatically detects the SmartEye within its Observe Camera menu. The mount must also be connected to the same network, which typically involves configuring the mount’s hand controller to link to the SmartEye’s Wi-Fi. Although the steps vary slightly depending on the mount model, the general procedure is straightforward, with clear instructions provided in the SmartEye’s interface.

The benefits of this integration are significant. With SkySafari’s SkyMap interface, users can perform plate solving to accurately determine the telescope’s position in the sky. By analyzing the stars visible in the SmartEye’s frame, the device calculates the exact pointing coordinates, allowing for precise alignment and object centering. Users can then select any target from the SkyMap, initiate a GoTo slew, and be confident that their telescope will land exactly on the desired object. This level of control and accuracy brings the convenience of modern smart telescopes to traditional setups without requiring new hardware.

Finally, for more advanced users, the SmartEye functions as a conventional cooled deep-sky imaging camera via the ASCOM Alpaca protocol. This allows the device to be integrated into established astrophotography workflows using software like NINA or any Alpaca-compatible program. When connected to the same network as the imaging computer, the SmartEye appears as a selectable camera within the software, providing full control over cooling, exposure settings, and image capture. While Wi-Fi connectivity imposes some limitations for bandwidth-heavy applications like planetary or lucky imaging, the SmartEye performs well for long-exposure deep-sky work, leveraging the IMX533 sensor’s high sensitivity and low noise characteristics.

A key advantage of this mode is the ability to switch between deep-sky imaging and visual observing without changing hardware. After a dedicated imaging session, users can simply transition back to eyepiece mode for an interactive, real-time experience, making the SmartEye uniquely versatile compared to traditional astro cameras.

Complementing these modes is the SmartEye’s web dashboard, accessible via a browser at smarteye.local/dashboard when connected to the device’s Wi-Fi network. The dashboard provides a user-friendly interface for configuring settings, monitoring live stacking progress, adjusting exposure times, and managing cooling temperatures. It offers an alternative to the astro crown for those who prefer working from a phone or computer. A guest view mode allows multiple users to follow the live stacking session on their own devices without altering any settings, making the SmartEye ideal for outreach events, classrooms, or star parties where groups can observe and learn together.

Throughout her review, The Space Koala highlights the SmartEye’s strengths, emphasizing how it bridges the gap between visual observing and electronically assisted astronomy.
