Shelyak Star'Ex High-Resolution Optical Kit

The Star’Ex High Resolution (HR) optical kit includes the optical elements to make your own Star’Ex HR instrument and take your first star spectra.

With Star’Ex (Star’Explorer), create your first High Resolution (HR) spectrograph to observe the spectrum of stars and not just take images of them!

The Star’Ex project:

Star’Ex is a project proposed by Christian Buil, in line with Sol’Ex. A dedicated site provides all the necessary information to assemble and operate this instrument.

You manufacture the parts by 3D printing (or have them made by a specialist), and then you assemble the instrument with the optical elements of this kit.

This kit includes all the optical elements needed to make a Star’Ex HR, including slit, grating, lenses, guide elements, etc.

In addition, this high-performance device offers several “wide slit” slit widths to adopt the Star’Ex configuration to the size of your telescope and the desired spectral resolution.

Note: With this optical kit, you also have all the necessary elements to make a Sol’Ex (we recommend that you start by making a Sol’Ex: it would be a shame to miss out on marvellous images of the Sun!). You can find more information about the Sol’Ex & Star’Ex project here.

If you already a Sol’Ex: 

Just purchase the “Star’Ex HR Optional” optical kit and transform your Sol’Ex into a Star’Ex.

Please Note: This is a DIY Assembly Kit, not a complete or assembled product. FLO will only accept 30-day returns on Unopened and Unused Kits
