The Lodestar PRO is an upgraded version of the very popular Lodestar & Lodestar X2 autoguider. The original Lodestar X2 uses the same ICX829 ExView2 CCD chip from Sony as the Lodestar PRO which offers excellent sensitivity and read noise. With lower readnoise and faster downloads, the effective sensitivity of the new Lodestar PRO makes it even easier to find faint guidestars making this still the best choice Autoguider on the market.
