Shelyak - Star'Ex HR Optical Kit

Meant to capture and observe bright objects, the HR model of the Star'Ex is best for bright galaxies and stars.  The Star'Ex was developed by Christian Buil and is intended to make spectroscopy accessible but providing you with the high precision optical components, and you 3D print your own housing.  Detailed instructions are included.  

As a modular system, users have the freedom to creatively reconfigure the optics and combine them with components from the Sol'Ex for a tailored experience.  Great for both experienced users who would like to experiment more, and beginners who would like to understand optical systems and spectroscopy better.  

• Spectral resolution: R = 700 to R = 30,000 depending on the slit width chosen (R = wavelength / spectral finesse)
• Wavelength range: 400 nm – 700 nm
• Internal reduction ratio: 125 : 80
• 10µm slit for maximum resolution, or 15, 19, 23 or 35µm slit, depending on your telescope.
