Handbook for the TRIUS SX-825      Issue 1 January 2015 

 

 

both planetary and deep-sky imaging, especially with an H-alpha filter. The H-alpha QE is about 65%, 
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. 

 

 
 
 
 

‘Quick Starting’ your TRIUS SX-825 system 

 

Please note, the TRIUS SX-825 is the successor to the TRIUS SX-9. The drivers and file formats 
are identical so within our software and other third party software, your SX-825 camera will be 
identified as an H9 or SX-9 derivative.  

 
In the shipping container you will find the following items: 
 

1)

 

The TRIUS SX-825 camera head. 

2)

 

A universal AC power supply module. 

3)

 

A USB camera cable. 

4)

 

An adaptor for 1.25” drawtubes, with a 1.25” filter thread. 

5)

6)

 

A guider output to guider port RJ12 lead. 

7)

 

Three short USB leads for connecting to the hub ports. 

8)
