Wedge question

Hi,
Is the function of using a wedge (I have a LX200 10") only for photography? Or is there another advantage to using one?
Thanks . . . Dave

the wedge provides the means to use the scope in an equatorial configuration. the advantage is that only the right ascension axis needs to be moved by a drive motor. this provides significantly more accurate tracking, especially important for long duration imaging actvities, such as photography (both CCD digital and film), photometry, spectrometry, or other such applications.
