    CCD KODAK KAI-340 - Mono or Color

    The ST-i uses a Kodak CCD sensor with low noise and high quality 'class 1. The KAI-340 has a read noise of only 9 e in this camera. This and 'the same sensor used as a guide in new and AllSky STX-340. It has a resolution of 648 x 484 pixel square by 7.4 microns. The anti-blooming and 'standard.

    CosଠKodak describes the performance of this sensor, "" Designed for imaging applications more' challenging, this sensor has additional features such as the electronic shutter, with peak quantum efficiency of 55%, read noise and dark current very low. These features provide a sensor sensitivity 'outstanding and make it ideal for various application list as scientific ones. ""

    Shutters electronic and mechanical

    The sensor ST-i has an electronic shutter to enable very short exposure times, up to 0.001 seconds. Most similar cameras of other brands possesses only this type of shutter because of the constructive difficulty (and cost) that involves the addition of a mechanical model. However, the ST-i also features a mechanical shutter to allow the camera to automatically remove the dark frames. This feature greatly improves the performance of ST-especially in the application of the guider. The cooling of the sensor is not necessary for typical use in court poses guider or ripredere planets and the moon, but the possibility remains that some hot pixels can be noticed during the guider. The abilities to capture and automatically subtract the dark frame allows for a perfect sky background and then you can use the stars to guide less bright. Finally, while the cameras of more economical driving using an analog-digital converter 8 or 10 bits, the ST-i uses a 16 bit converter high Furnishings for higher resolution and greater dynamic range.
