Star Analyser 100 Grating

Star Analyser 100 (SA-100) grating is designed specifically for amateur astronomical spectroscopy. It can be mounted on your telescope just like any other 1.25″ filter. It’s is easy to use and works with most cameras. Capturing the spectrum of a star is easy! Use our grating, a DSLR or small telescope, and our award-winning software.

Star Analyser 100 is a diffraction grating with grooves that are spaced at 100 lines/mm. The grating is durably mounted in a standard 1.25″ filter cell and is protected on both sides with anti-reflection coated glass.

You don’t have to have to be a PhD to capture and understand the spectra of stars! With our gratings and software, it’s amazingly easy. We have customers using these gratings on webcams, DSLRs, modern video astronomy cameras, and of course FITS images from cooled or uncooled astronomical CCDs.
