Such a powerful combination of durable materials, ease-of-use, and outstanding quality gives the SmartEye a professional feel that is sure to impress astronomers of all experience levels.
Transform Your Small Telescope
One of the biggest benefits of live stacking is the ability to see big details from small apertures. Where aperture used to be the sole determining factor of an observer's light-gathering ability, now you have access to time.
More time for photons to hit the SmartEye’s sensor means more details in the eyepiece! You’ll see vibrant details in distant galaxies and nebulae that were previously inaccessible with smaller telescopes. Or even with larger ones!
This redefines the boundaries of visual astronomy, enabling everyone to explore the cosmos with unparalleled clarity and ignite their passion for astronomy.
Defy Light Pollution & Observe from Anywhere
Even in the darkest of skies, human eyes will always struggle to see as much detail as a camera sensor. This is especially true in high-light pollution areas. But with the SmartEye’s sensitive CMOS sensor and the ability to live-stack, you can now use any narrowband, multi-band, or even broadband light pollution filter.
With the SmartEye’s onboard color calibration and image analysis software, these filters will still produce beautiful views. You can also choose to save the files for processing at a later time - you may end up with some pretty fantastic data!

Frequently Asked Questions
What types of telescope work with SmartEye?
SmartEye is compatible with all telescopes that are able to come to focus with a regular eyepiece. It is compatible with 2" focusers out of the box, but the 2" barrel on the SmartEye is removable, enabling use with an optional 1.25" barrel. Commercial 1.25" to 2" telescope eyepiece adapters are also available. For the best results it is also recommended to use telescopes that have a focal ratio of f/7 or faster. For longer focal length telescopes like Schmidt-Cassegrains (SCTs), focal reducers can help achieve this recommended ratio.
Do I need a computer to use SmartEye?
