Optical kit for SUNSCAN spectroheliograph by STAROS Projects
This is the core optical kit for the innovative SUNSCAN spectroheliograph from STAROS Projects. It provides the essential optical elements required to construct a modern, stand-alone instrument capable of imaging the Sun in any wavelength you choose. Once assembled, the complete SUNSCAN system is designed to be controlled wirelessly through a dedicated smartphone or tablet application, bringing advanced solar analysis into the hands of the dedicated amateur.
Build a Custom-Wavelength Solar Spectroheliograph
A spectroheliograph builds a monochromatic image of the Sun by scanning it, slit by slit, capturing only the light from a specific spectral line. This kit is the foundation of that capability, enabling you to assemble an instrument that goes beyond common H-alpha or Calcium-K filters to explore other interesting lines like Sodium D or Helium D3.
By undertaking the SUNSCAN project, you can create a highly specialized solar telescope tailored to your specific research or imaging interests. The finished instrument allows you to see solar features like prominences, filaments, and plage with unique contrast depending on the wavelength selected.
The Optical Foundation for Your SUNSCAN Project: What's Required
This product provides the specialized optical components only. It is intended for the dedicated hobbyist ready to take on a rewarding DIY project. To complete the SUNSCAN spectroheliograph, you will need to source several other components separately.
Please be aware that this kit does not include the 3D-printed structural parts, focuser, imaging camera, Raspberry Pi 4 controller, tripod, or other complementary hardware. These items must be acquired independently to complete the instrument as designed by STAROS Projects.

What exactly is in the SUNSCAN Optical Kit?
This kit contains only the core optical elements required for the STAROS Projects SUNSCAN spectroheliograph. It is not a complete instrument. You will need to supply all mechanical parts, electronics, and hardware separately.
What else do I need to build the full SUNSCAN spectroheliograph?
To complete the project, you must source several items independently. Key components not included are:
-
3D-Printed Parts: The main body and structure of the instrument.
-
Electronics: A Raspberry Pi 4 (RP4) for control, plus an imaging camera.
-
Hardware: A focuser, tripod, and various fasteners.
Is the SUNSCAN project suitable for a beginner?
This is an advanced DIY project best suited for experienced astronomical instrument makers and solar imagers. It requires sourcing parts, 3D printing, and assembling electronic and optical components. Familiarity with spectrograph principles is highly recommended.
How is the completed SUNSCAN instrument controlled?
The SUNSCAN spectroheliograph is designed by STAROS Projects to be a stand-alone unit. It is controlled wirelessly via a dedicated application on a smartphone or tablet, which communicates with the onboard Raspberry Pi 4.
Can I use the SUNSCAN to image in the H-alpha line?
Yes. The principle of the spectroheliograph is to allow imaging at any user-selected wavelength. You can configure the instrument to image in the hydrogen-alpha line (656.3 nm) as well as other spectral lines of interest, such as Calcium-K, Helium D3, or Sodium D lines.
Where can I find the plans for the 3D-printed parts for the SUNSCAN project?
The design for the SUNSCAN is an open-source project from STAROS Projects. You should refer to their official project page or community forums for the latest STL files and assembly instructions.
