The Cross Flow Fan System™ is a patented method of achieving steady, crisp images in a reflecting telescope far before the mirror has reached thermal equilibrium. This is especially useful for planetary and lunar viewing. Regular fans only help reduce mirror cool down time. The Cross Flow Fan System™ has a controlled air flow which will produce steady images within 5 to 15 minutes of exposure to the cold night temperatures.  With a refined and controlled air flow, an observer using the Cross Flow Fan System™ can be using their scope while others are still waiting for the cool down, and also get more steady images throughout the night.

Provided here are details of the Cross Flow Fan System™, in addition to engineer drawings of the product assembly.
