The perfect camera for short focal length refractors

The latest addition to the TRIUS camera range, the PRO-834 uses a 12 megapixel Sony CCD with 3.1uM square pixels. This very high resolution chip is well suited to short focus optics, especially compact refractors. The new PRO board design has given this camera an exceptionally low readout noise figure of better than 3 electrons RMS and a fast download time of only 5 seconds in full resolution mode.

CCD Type: Sony ICX834AL EXview II CCD with ultra low dark current and vertical anti-blooming
CCD Full resolution pixel data: Pixel size: 3.1uM x 3.1uM, Image format: 4240 x 2824 pixels
CCD Image area: 12.49mm (Horizontal) x 9.99mm (Vertical)
CCD quality: Grade 1 or better – No bad columns, no dead pixels, no more than 50 ‘hot’ pixels (saturated in <10 seconds)
Spectral Response: QE max at 580nM (~77%), 50% roll-off at 360nM and 770nM
>Readout Noise: Typically ONLY 3 electrons
Full-well capacity: Greater than 9,000 e- (unbinned)
Anti-blooming: Overload margin greater than 800x
Dark current: Less than 0.002 electrons/second @ – 10C CCD temperature
Data format: 16 bits
System gain: 0.25 electrons per ADU
Computer Interface: USB
Image download time Typically 8 seconds at full resolution.
Power requirements: 240VAC @ 12VA, or 12VDC @ 900mA max
Cooling system: Regulated set-point cooling supply with thermoelectric cooler to give a minimum CCD temperature of approximately -30C below ambient.
Size: 5 x 70mm black anodised aluminium barrel with 42mm ‘T2’ thread at the CCD window end & input/output plugs at rear. CCD alignment screws are provided for setting the chip parallel to the focal plane.
Weight: approx. 450g

Introducing the Starlight Xpress TRIUS PRO Series of cooled CCD cameras to our product portfolio.

The TRIUS range of cameras was introduced in 2014. These were the first cameras on the market to incorporate a powered USB 2.0 hub in the rear of the camera to enable the user to connect their USB filter wheel and guide camera directly to the camera rather than multiple cables back to the computer – simplicity and convenience.

The new TRIUS PRO Blue series follows on from that success. We have redesigned the electronics to give even lower read-noise figures and faster downloads. With the Sony CCD cameras, we are now getting read-noise figures that are better than most CMOS cameras (when used at unity gain), along with 16bit data and significantly better dark-noise figure thanks to the impressive cooling. Dark frames really are a thing of the past, making calibration frames optional rather than compulsory, giving you more time to capture data and process your images.
