[Makestreme] had always wanted to own a nice telescope, but found that budget would not stretch to anything above a cheap model with a limited 50 mm aperture. Wanting a better view of the heavens, the way forward was obvious—it was time to build a better telescope, instead!
The build is based around a 114 mm diameter mirror sourced from Amazon. It’s assembled inside a length of 5-inch PVC pipe of just under a meter to suit the 900 mm focal length of the concave reflector. 3D printed components are used to mount the mirror and control its position for proper focus and collimation. Traditionally, a reflector based telescope would use a mirror and eyepiece to provide a view to the user. However, [Makestreme] built this as a smart telescope, instead integrating a Raspberry Pi Camera Module 3 at the focal point. It’s connected to a Raspberry Pi Zero 2W, running off an 18650 lithium-ion cell and a 5 V boost module for portability. The Pi runs a Python script that hosts a small web server allowing access to the live camera feed along with controls for brightness, exposure, and gain. [Makestreme] then uses apps like SkyMap and SkEye to help aim the telescope at astronomical elements of interest.
If you’ve ever wanted to explore the heavens from down on Earth, building your own telescope is a great way to start. A camera-based build like this one can be a bit simpler than traditional builds, too, without the fuss of having to install an eyepiece.
Wow SkEye is still around and being updated after over a decade? Bought the paid version long ago to support the creator.
I havent used it in many years because phone accelerometer just sucked back then.
But I do occasionally use that on Sky Safari. They still suck but can get you into the right ballpark naked-eye when you find yourself looking for a thing in twilight.
Looks like my old Meade DS114. Except probably not full of all the backlash.

Executive Summary
Full Take
The narrative presents an exploration of bridging traditional amateur astronomy with modern embedded systems, framing a physical build as a path toward advanced observation. This speaks to a pattern where practical constraints (budget) drive innovative technical solutions, shifting the focus from acquiring expensive, conventional instruments to engineering custom digital tools. The integration of open-source hardware (Raspberry Pi), accessible components, and software control exemplifies a counter-movement against proprietary, high-cost astronomical equipment by emphasizing agency and customization in observation. The reflection on legacy tools like Meade suggests a tension between established methods and novel, digitally mediated experiences. The implication is that the pursuit of knowledge can be democratized through accessible fabrication and software integration, suggesting that cognitive sovereignty over one's observational experience relies less on optical perfection and more on adaptable technical skill.
Bridge Questions: What are the long-term epistemological differences between observation facilitated by direct optics versus observation mediated by digital sensors? How does the reliance on external software (SkyMap) influence the internal development of an observer’s innate spatial reasoning skills? If custom builds democratize access, what new forms of authority or critique emerge within the community that values bespoke technological solutions over standardized instruments?
