RSpec Star Analyser 100 Astronomical Diffraction Grating, SA-100
The Paton Hawksley Star Analyser diffraction grating splits starlight so you can study stellar spectra. This astronomical quality grating is ruled with 100 lines/mm, making it an ideal device to see the entire spectra of a star or planet.Mounted in a 1.25" standard filter cell, use the Star Analyser grating with a webcam, astronomical FITS camera or (with our AD-55 adapter) your DSLR. The grating is blazed to maximize the brightness of the first order specta.Capture the spectra of Vega. See the methane atmosphere on Neptune. Detect the red shift of a quasar and the Doppler shift of bright supernovae.You can process your images in our RSpec-Astro, our real-time spectroscopy software.
