An equatorial wedge is for astrophotography exposures longer than about 5 minutes. A wedge permits precise polar alignment of your telescope in equatorial mode, as compared to Alt/Az mode. This eliminates field rotation in long-exposure photographs by allowing you to align the telescope''''s'' axis of rotation with the Earth''''s'' axis of rotation. Fits all LX models 8"-14".

This die case aluminum wedge includes fine adjusters, no-tool knobs and a compass for faster aligning on the pole.
