True CCD Astrophotography Camera
The TRIUS PRO825C uses the new version of the legendary ICX285AQ – used in thousands of H9C cameras since 2003. The new chip offers an excellent QE of about 75% in the yellow visual band and an extremely good H alpha QE. The image format and pixel size are the same as for the SX9C camera.
There’s lots of advantages of using a CCD chip for deep-sky imaging compared to CMOS cameras.
Please note this camera uses a “Grade 1” CCD chip.
