Christian Buil have design a new spectroheliograph in 3D print.
All detail here :

http://www.astrosurf.com/solex/

Sorry this website is in only in french for the moment
And a message from Christian Buil :
-----------------------------------------
Sol'Ex (for Solar Explorer) is a small instrument that you can make in 3D printing and with a minimum of means. It allows you to observe the solar atmosphere in the Hydrogen line, but also any other line of your choice. Of course here, it is question of a spectrograph, more precisely, a spectroheliograph.

First, a web site exists, which details the reasons for the project, how to make the instrument and how to use it. See here :

http://www.astrosurf.com/solex/

(In French langage for the moment, but many illustrations are present and easy to translate).

Of course, to get to the end of this achievement you must by one means or another, you can make small parts in 3D printing, either because you have a printer, or, through friends, members of a club, your company, a local FabLab, etc. You can download all the necessary files from the Solex site. Today there is no other way, because there is no mechanical parts kit.

On the other hand, a kit of the necessary optical parts exists, which will considerably facilitate your task if you want to get started. This kit includes a high performance 10 micron slit, a set of two lenses that I calculated especially for the Sol'Ex project and made specifically (I included special glasses in the formula for maximum performance), a 2400 lines/mm diffraction grating.

It will cost you a little less than 400 euros including tax (excluding shipping costs). You will find a link to a product sheet from Shelyak Instruments company on the Solex website. You benefit from this preferential rate until February 28, 2021 as part of a subscription.

I am aware that this may represent a fairly high sum for equipment to build yourself (know that the maximum has been done to lower the cost as much as possible), but I hope that reading the site will show you that the said sum will be quickly paid for itself (incidentally, we can consider doing much more than solar imaging, you will see, stellar spectrography for example).

The optical kit subscription ends tonight at midnight. It is not too late to order it but afterwards it will be offered at 520 € incl. VAT + shipping costs.

Hello everyone,

A new optical kit for the Sol'Ex project initiated by Christian Buil is now available and includes elements optimized for the Star'Ex, (to take stellar spectra) and the optical elements to build an autoguiding module. There are of course also all the optical elements necessary to build a Sol'Ex for Sun scans, but the 80mm lens has been optimized for more efficiency in the blue of the spectrum (the H and K lines). The 80mm lens will also give better results in stellar spectroscopy (Star’Ex version)

The kit is now available here :
https://www.shelyak.com/produit/es0027- ... t/?lang=en

And for those who already have the original optical kit, it's possible to get an upgrade of the original kit which includes the additional elements to achieve a star'Ex here:
https://www.shelyak.com/produit/se0257- ... e/?lang=en

The Sol'Ex project website has been completely redesigned by Christian Buil, with many video tutorials in support, you can consult it here:
http://www.astrosurf.com/solex/sol-ex-p ... on-en.html

Here's a video showing the use of the Star’ex version : https://youtu.be/SaRHc7dgSMo

An excellent video that will show you that you can easily make stellar spectra with a small instrument. Christian shows you step by step how to obtain a Vega Spectrum with a Star’Ex.

I remind you that there is also a discussion list dedicated to the Sol'Ex project, to register:
https://groups.io/g/Solex-project

The Sol'Ex adventure continues!
