Whoppshel Spectroscope

Whoppshel detourThe Whoppshel is the ultimate spectroscope in the Shelyak range. A very high resolution instrument (R >25.OOO), it is intended for large instruments (telescopes over 700mm in diameter). A fibre-optic ladder spectro, it is particularly suitable for “exoplanet hunting”.

The whoppshel is a fibre optic spectrograph with a resolution of R >25.000. The various elements of the spectrograph are mounted on an optical bench.

Here are 2 articles on tests that have been carried out on 2 different telescopes:
