Starlight Xpress Trius SX-16 CCD Camera
|Starlight Xpress Trius SX-16 is a medium format CCD camera with a 2048x2048 pixel array of 7.4 micron pixels well suited to Schmidt-Cassegrain telescopes. |
The SXV-H16 is a departure from the normal SX line of Sony CCD based cameras. As Sony do not manufacture a large mono chip, we researched the available devices and decided that the Kodak KAI4022M was the best option for a new mono camera. To reduce the negative effects of the greater Kodak dark signal, we have used a two stage Peltier cooler for a 10 degree reduction in the CCD temperature, and a new high-speed USB2 interface circuit to greatly reduce the download time. The fast download minimises the visibility of bias frame artefacts, such as hot columns and the top to bottom gradient that is commonly seen on such chips. We think that the result is a highly satisfactory mono camera which overcomes the lack of suitable Sony mono devices.
Dr Dietmar Hager has tested and reviewed the SXVF-H16. His conclusions can be found at www.stargazer-observatory.com/reportsCCD-h16-engl.htm
