Sol’Ex should be mounted on a small telescope (with a focal length of 450mm max), to see the whole Sun in a single image, but a longer focal length is possible and will give more detailed images of portions of the disk. This project includes automatic image processing software: the result appears on the screen in just a few clicks. Sol’Ex works on the principle of a spectroheliograph: the image is built up line by line by scanning the image of the Sun (it’s the same principle as a photocopier, except that in this case the copy is an image of the Sun).\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eThe\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eSol’Ex optical kit\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eoffered by Shelyak includes all the optical components needed to build the instrument: slit, grating, lenses, etc. You’ll need to source the parts independently in 3D printing, or build them yourself if you have a printer (STL files available on the Sol’Ex website).
