About JSol’Ex

JSol’Ex is a solar images processing software for Christian Buil’s Sol’Ex. It is capable of processing SER files captured with this instrument in order to produce images of the solar disk, in a similar way to what Valérie Desnoux’s INTI, which is the official software for processing your Sol’Ex images, is doing. JSol’Ex is primarily designed to process images for Sol’Ex, but it might work properly for other kinds of spectroheliographs.

JSol’Ex is free software published under the Apache 2 software license. It is written in en Java and provided for free without any warranty.
