The small accessory that gives you a low-cost start in astronomical spectroscopy. You work under the same conditions as in imaging, simply by adding the StarAnalyser in front of the camera or DSLR. Each star in the field is then accompanied by a spectrum, and you can observe differences from one spectrum to the next. This SA200 version is particularly suitable for mounting in a filter wheel, where the StarAnalyser is very close to the sensor.
