Grating Filters & Spectrograph Kits

The Star Analyser is a transmission diffraction grating in a standard 1.25-inch filter cell. Thread it in front of your camera or into a filter wheel, point at a bright star and the image shows the star plus its spectrum stretched out beside it. In one evening you can see the difference between hot blue stars and cool red ones, the hydrogen lines of A-type stars and the bands of red giants.

We carry the Star Analyser 100 and 200, the 3.8° prism that reduces aberrations in fast systems, the UVEX order filter kit and the LISA near-infrared conversion kit.

Star Analyser 100 or 200?

  • Star Analyser 100: 100 lines/mm. Best for cameras close to the sensor and for small sensors with telescopes.
  • Star Analyser 200: 200 lines/mm. Twice the dispersion, suited to filter wheels and larger sensors at a longer distance.
  • Spacing: The distance from grating to sensor sets the spectrum length. Spacers let you tune it.

Star Analyser: Frequently Asked Questions

Do I need a tracking mount?

A tracking mount helps, but short exposures of bright stars work even on simple setups.

What software processes the spectra?

Free software such as RSpec, BASS and ISIS reduce Star Analyser spectra.
