Shelyak Alpy Spectroscopes

Shelyak Alpy spectroscopes are compact, modular long-slit spectroscopes for amateur and educational spectroscopy of stars, nebulae and comets. The Alpy 600 gives low-resolution spectra across the visible range, and the Alpy 200 is a lower-resolution version suited to fainter targets.

Modules let you build the instrument you need: a guiding module with a slit mirror, a calibration module for wavelength reference, a Barlow lens, slits from 23 µm to 50 µm, and C-mount or ST8/10 camera adapters.
