Agile Autoguider 4+‎

Agile Autoguider corrects the mechnical guiding of your telescope to achieve a high guiding precision. The iPhone is attached to the finder scope of your telescope and tracks a guide star via the rear camera. If the guide star drifts, an actuation is computed to bring the telescope back to position. Continuous corrections enable you to take long-exposure photos with dot-shape stars, or to train the periodic error correction of your telescope mount.
