Shelyak Instruments was created in 2006 to design and distribute scientific and educational instruments, as well as accompanying services. The company’s primary objective is to develop spectrography in the world of astronomy, for both amateurs and professionals. Shelyak Instruments was created by François COCHARD and Olivier THIZY, two amateur astronomers with decades of passion and experience. We designed the Lhires III in collaboration with Christian Buil, and handled all distribution through AUDE association. The success of this instrument led us to create the company, and then to develop a whole range of products to meet the most varied needs.
