TS-Optics primary mirror ventilation for mirror telescopes
Accelerate the temperature adaptation of your telescope by roughly 50% with this light and quiet fan. You are also reducing the so called "Tube seeing", by introducing a constant but gentle stream of air. The image quality of the telescope is improved as well as ready to use faster.Using the four included screws the fan is simply installed at the backside of the primary mirror cell. Alternatively you can use double-sided tape.
Alternative usage with a closed backside
Mount the fan in such a way, so it doesn´t blow air, but rather sucks the air off. This makes sense with a telescope that has a closed backside. As a result warm air is quickly removed from the system.| Fan dimensions: | 80 x 80 x 25 mm |
| Distance between holes for installation: | 71 x 71 mm |
| Power supply: | 12 V DC (via 8x standard batteries - D-cells/mono-cells) |
