About KatEyes

With KatEyes digital eyepiece you can point your telescope at a faint nebula that is invisible to the naked eye, and within seconds, watch it appear in vibrant detail and color right inside the eyepiece.

It is powered by a Raspberry Pi 5 and a high pixel density OLED screen. Currently, it utilizes OpenLiveStacker to automatically stack images in real-time.

Choose Your Path

Currently, I'm developing two core versions. Both allow you to use your own astronomy camera via USB.

1. KatEyes Bino (Digital Binoviewer)

The ultimate immersive experience. Use both eyes to view the screen with simulated 3D depth effects. Additionally, using both eyes increases the perceived brightness of the image by ~40% (binocular summation).

2. KatEyes Mono (Digital Monocular)

A compact, lightweight version for quick setup and cyclops-style viewing. Also, should be a bit more affordable.

Future Plans

Integrating the IMX585 sensor will eventually produce a truly standalone eyepiece. However, for now, I'm focusing on compatibility with your existing gear.

The Ready-to-Use Route

Not everyone has the time to build electronics. I will be offering fully assembled units.

Please note: As a one-person operation, these will be produced in small batches.

The DIY Route (Free)

If you have a 3D printer you can build this yourself. I will be releasing the plans, parts list, and software instructions for free.
