The little brother of the Shelyak Spectroscoop Alpy 600 for spectra of very faint objects with a resolution of around R=130.
The Alpy 200 opens the door to target astrophysics at the edge of the universe, enabling you to produce spectra of faint objects such as supernovae, quasars and other faint galaxies.The Alpy 200 is a compact (just a few cm long), high-performance, modular and easy-to-use slit spectroscope. It’s a true scientific instrument that will stay with you for a long time.Its resolving power (R=130) enables it to cover the entire visible range and even a little more (typically from 375nm in the near UV to 750 nm in the near IR). The dispersing element is a grism, i.e. the combination of a prism and a diffraction grating (200gr/mm).
The slit isolates a fringe from the light source. This brings several advantages: you isolate the object you wish to observe, you can work on extended objects (nebulae, planets), you can make calibration spectra… thanks to the slit, the quality of the spectrum obtained becomes independent of observation conditions (seeing, telescope tracking problems, etc.). The Alpy 200 is supplied with several interchangeable slots (see photo opposite), to cover a wide range of observation situations.
The compactness and lightness of the Alpy 200 make it compatible with small instruments (telescopes or refractors, from 80mm diameter), on modest mounts.
The Alpy 200’s optics have been specially designed to give the best image quality in the entire visible range, with a wide aperture (F/4). You’ll be amazed at the amount of information that can be extracted from such a small spectroscope! This quality is such that many scientific publications are based on observations with the Alpy 200.
The Alpy 200 is robust, insensitive to temperature variations, and requires few adjustments. This makes it an easy-to-use spectroscope, for fast, spectacular results. Operation is further simplified by the free Demetra software, which accompanies your observations from acquisition to data reduction.
The Alpy 200 is modular, meaning it can be used in a variety of ways. With naked eye (daylight), with a digital camera (DSLR), with a CCD camera, on a table or behind a telescope, the possible configurations are numerous, and the interfaces are standard.
