SCT Cooler Photos 
An associate holding an SCT Cooler sized for a 10" SCT. 
SCT Cooler installed in an LX-200 using an SCT to 2" adapter for enhanced air flow.

Air outlet holes in the end of air delivery duct. Note that the holes are angled back slightly to direct the air flow towards the back of the optical tube. The angle is enough to circlulate air throughout the tube without pointing it directly at the primary. 
The end cap of the air delivery duct showing how it is clearly marked for the size of telescope it is to be used with. 
Closeup of the SCT Cooler blower body which clearly shows the exhaust grooves. These exhaust grooves allow the air to exit the optical tube whether a 1.25" or 2" visual back is used. 
Closeup of the intake side of the fan. While it may look similar to a common "computer fan", the SCT Cooler uses a high-output ball-bearing blower with reverse polarity protection. The air filter is located behind the fan and is replaced (infrequently) by simply removing the 4 screws shown here. 
SCT Cooler with the air delivery duct removed. Note the allen wrench sticking out of the set screw. Using the SCT Cooler with different sized telescopes requires only a different length duct. Extra air delivery ducts are available separately.
