It achieves this by capturing diffraction orders 32 through 53 simultaneously, using a 50µm fiber for the target and a 200µm fiber for calibration to ensure maximum stability for demanding applications like exoplanet radial velocity studies.\u003c\/p\u003e\n\u003cp\u003eThis instrument is designed for observers who cannot compromise between spectral range and resolution. Developed from experience with professional spectroscopes like Musicos and Narval, the eShel III provides a turnkey solution for advanced astrophysical research.

A cross-disperser then stacks these orders across the camera sensor, allowing you to capture the entire visible spectrum from 390nm to 700nm in a single exposure. This multi-order spectrum provides comprehensive data, ideal for monitoring variable stars or classifying stellar objects without sacrificing detail.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eThermally Stable Radial Velocity with a Fiber-Fed Design\u003c\/h3\u003e\n\u003cp\u003ePrecision in spectroscopy, especially for exoplanet detection, requires extreme stability. The eShel III uses a 20-meter-long optical fiber to physically separate the spectrograph from the telescope, allowing the instrument to be placed in a temperature-controlled environment. This isolation from thermal fluctuations and mechanical vibrations at the telescope is critical for accurate radial velocity measurements.\u003c\/p\u003e\n\u003cp\u003eThe complete system includes the F\/6 Fiber Injection and Guiding Unit (FIGU) for precise starlight injection into the 50µm object fiber, and a dedicated calibration module with a Thorium-Argon (ThAr) lamp. The calibration spectrum is fed through a separate 200µm fiber, providing a stable reference for sub-pixel velocity measurements.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eIntegrated Control: Remote Acquisition and Data Reduction Software\u003c\/h3\u003e\n\u003cp\u003eThe eShel III system includes Demetra, a powerful and free software suite for MS Windows that manages the entire observation workflow. From the control room, you can remotely operate the FIGU and the calibration module, automate image acquisition, and process the complex echelle spectra.

A camera like the \u003cstrong\u003eATIK 460EX Monochrome\u003c\/strong\u003e is often recommended, as its sensor size and pixel characteristics are well-matched to the instrument's output when used in 2x2 binning mode.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eHow would I use the eShel III to study the radial velocity of a star like 51 Pegasi?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eTo measure the subtle Doppler shift caused by an exoplanet, you would use the fiber-fed system to ensure thermal stability.

The \u003cstrong\u003eR \u0026gt; 10,000 resolution\u003c\/strong\u003e is high enough to detect the small wavelength shifts, and the Demetra software would be used to precisely measure these shifts against the stable ThAr reference lines, revealing the gravitational \"wobble\" induced by its planet.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eCan the eShel III capture the spectrum of a pulsating star like BW Vulpeculae in a single exposure?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes, this is an ideal application for the eShel III.
