What is it?

The Outback Cooler uses a Peltier device to pump heat from the DSI imaging chip to the rear mounted heat sink. This enables the Outback to reduce the temperature of the CCD below the ambient temperature and subsequently significantly reduce the noise level in the images. The Outback regulates the temperature of the CCD so that it remains constant at the preset value through out the imaging session. In this way only one set of dark frames needs to be taken for the session.

There are now three versions of the Outback Cooler in two series. Outback (for DSI I and II) and Outback III (for the DSI III)

Razorback	Fan cooled heat sink
Platypus	Water cooled heat exchange
Dingo	Uses either water or air cooling (User selectable)

The Outback Cooler replaces the factory convection heat sink built into the DSI/DSI Pro and DSI II/DSI II Pro rear case and the Outback III for the DSI III/DSI III Pro. Both Outback and Outback III give similar performance. You will need to open the DSI case and fit the Outback Cooler to the front section of the DSI camera via the same four mounting bolts. This obviously has warrantee implications for you DSI camera and you are taking full responsibility for the modification and continued function of your DSI camera. The DSI camera functionality, circuit board or USB interface are not changed in anyway. The outback simply replaces the rear case of the DSI camera and runs off a separate 12V power supply. All control of the Outback is via the single button and indicator LEDS shown below:

The Outback Cooler operating range to achieve a regulated CCD temperature is indicated below:

Specifications:

Outback Cooler (Razor Back)

Power Supply	Requires a 12V 3 Amps supply (Cable supplied will car lighter plug) Allowable voltage Range 11 to 15 Volts Current draw 2.5Amps Max. Typical 1.75 Amps.
Cooling Capability	Cools CCD to 15 Deg C below ambient maximum.
Preset Cooling Range	20 to -10 Deg C in 5 Deg C increments
Regulation	+- 0.25 Deg C
Form Factor	Bolt on replacement back case for DSI, DSI Pro and DSI II, DSI II Pro
Weight	425g (adds 250g to DSI weight since original back is removed)
Size	The Outback is the same dimensions as the DSI body. The difference will be in the depth as the back is deeper than the original back Razor Back = 82mm (Measured from tip of T-Ring on the front of the camera to the rear extreme of the cooler)
User Interface	A Single button used to cycle through preset regulation temperatures and fan speed.
Indicator LED's	Indicates selected regulation and actual CCD temperature.
Fan Cooled	A small fan speed controlled to increase sustainable performance
Assembly/User Manual	See Instructions menu above.
