Handbook for the TRIUS PRO-825C Issue 1 September 2020
2
The TRIUS PRO-825C uses a Sony ICX825AK ‘EXview II’ progressive scan CCD, with
1392 x 1040 x 6.45uM pixels in a 8.8 x 6.3mm active area. This EXview II device has
an excellent quantum efficiency, with a broad spectral response peaking at around
77% in yellow light, and an extremely low dark current, well below that of any
comparable CCD currently available. While this device also has an excellent blue
light sensitivity, it has a strong infra-red response, which makes it ideal for all
aspects of both planetary and deep-sky imaging, especially with an H-alpha filter.
The H- alpha QE is about 50%, considerably better than other interline chips and
even greater than the popular KAF8300 CCD.
The full-frame download time is approximately 4 seconds and a binned 4x4
download takes only 0.5 seconds, so finding and centring are very quick and easy in
this mode.
Here is a diagram of the connectors to be found on the rear panel of the camera:
Please take a few minutes to study the contents of this manual, which will help you to
get the camera into operation quickly and without problems. I am sure that you want
to see some results as soon as possible, so please move on to the ‘Quick Start’ section,
which follows. A more detailed description of imaging techniques will be found in a
later part of this manual.
