Starlight Xpress Spectroscope SX with Lodestar X2 Autoguider (48690)

This compact spectroscope features a high-performance flat-field concave grating in a module measuring just 136 x 120 x 75 mm and weighing 1.2 kg. It includes a built-in Lodestar X2 guide camera and an argon-neon calibration lamp for precise wavelength calibration.

Both the input and output are equipped with T2 threads, making the unit compatible with most imaging cameras that use T2 thread connections. Starlight Xpress recommends pairing this spectroscope with the Trius SX-694 camera for optimal performance.

The spectroscope covers a spectral range from 340 to 900 nm across a 31 mm length, with a resolution factor exceeding 2000. This allows detailed analysis of astronomical spectra, suitable for both amateur and research-level observations.

This spectroscope is ideal for astronomers who need a compact, high-resolution instrument with built-in guiding and calibration features. Its compatibility with standard T2-threaded equipment and integrated guiding camera make it easy to use with a wide range of setups.
