These were the design goals for the ST-402ME camera: something simple and easy to use yet powerful enough to carry the "ST" model prefix. The new ST-402ME is seen above equipped with the optional T-thread to C-mount adapter ring and lens. For use at the telescope, a 1.25" nosepiece screws into the T-threads of the front plate.

The small size and light weight makes this camera very easy to handle and set up. A custom internal filter wheel and shutter lets you take dark frames and tri-color images automatically. Best of all, the low noise and extraordinary QE of the KAF-0402ME CCD makes this one of the most sensitive CCD cameras available to amateurs at any price. Simply put, there is nothing that can touch it in its class, except of course the dual sensor, self-guiding ST-7XME camera. The same technology that is used to achieve such high quantum efficiency in the KAF-3200ME CCD is also used with the same effectiveness in the KAF-0402ME CCD. With a peak QE of nearly 85%, this camera bows its head to no other when it comes to recording faint detail in dim objects.
