Hi,
Well, the DSI III Pro Outback Razorback Cooler finally arrived from Australia after it was rebuilt by Steven Moog to correct some problems with the first production models.
I have it mounted now and it seems to be working to specs. I did make a slight modification, I added a foam block to the case to insulate the metal original front case for the camera. The cooler was making the metal quite cool. So I figured that this indicated a heat leak and that insulating it would improve the cooling
characteristics of the unit. Indeed it did seem to help to achieve quick equilibrium and keep it there.
I have taken a set of darks at 10°c and 5°c and it is amazing how the 1 minute and 10 minute darks look almost the same.!
Here is a picture of the camera with the cooler, foam block, filter wheel and TV focal reducer. This is the configuration used for imaging. Note the felt seals on the filter wheel thumb knurl area, to keep out light or dust.
Total cost (new including focal reduce and wheel) of the unit as shown without filters is $1730. This is not bad for the performance that it provides.
It is about the same as an Atik 16HR (same chip, but with un-controlled cooling)without the filter wheel or focal reducer.,
This package represents a good value in a mid-priced camera with a nice size chip and FOV as well as small pixel size.
