But when you want to observe the spectrum of a star, a problem arises: how do you know if you’re pointing at the right star, and make sure the star is perfectly positioned in the slit?\u003c\/p\u003e\n\u003cp\u003eThe guiding module answers this question: it allows the telescope field and the slit (observed from the front of the spectroscope) to be viewed with a guiding camera. It is an indispensable aid for pointing as well as for guiding \u0026amp; autoguiding the telescope as soon as your observation lasts more than a few seconds.\u003c\/p\u003e\n\u003cp\u003eThe principle of the guiding module is simple: the standard slit of the spectro (Alpy 600 or UVEX) is replaced by a reflective, slightly inclined slit, which reflects the telescope image onto the guiding camera (or eyepiece, with the optional eyepiece holder).
