You can do astrophotography with the LX200 scopes in the standard altazimuth mode, but with longer exposure times, an effect called field rotation becomes evident. Stars at the edge of the field will appear as small concentric arcs or streaks on the film, rather than as star points. To prevent field rotation, your LX200 or LX200 GPS can be polar-aligned with the wedge. The wedge allows you to align the telescope's axis of rotation with the Earth's rotational axis. And this eliminates the effects of field rotation and gets the star streaks out. |
