Celestron USB Cooling Fan for Dobsonians
The Celestron USB Cooling Fan is designed for StarSense Explorer 10-inch and 12-inch Dobsonian telescopes. It helps cool the primary mirror to the outdoor ambient temperature faster, allowing you to enjoy sharper, better-focused views sooner. The fan mounts directly onto the rear cell of compatible telescopes and works with any USB power source, including portable power banks and AC wall adapters. Once the primary mirror has cooled and you’re ready to observe, simply disconnect the USB power source. For convenient storage and organization, the fan’s cable can be connected to the integrated storage clip when not in use.
Powering the Cooling Fan
Any USB power source can charge the cooling fan. Unlike other fans on the market, this USB Cooling Fan for Dobsonian Telescopes does not require an external, bulky 12V power source or disposable batteries. Â This fan uses less voltage (5V vs. 12V) than competing models. Still, our rigorous internal testing shows that the Celestron Cooling Fan provides better airflow and faster overall cooling compared to competitors.
Compatible Telescopes
The USB Cooling Fan for Dobsonian Telescopes is compatible with the StarSense Explorer 10” and 12" Dobsonian telescope and many other third-party Dobsonians and Newtonian Reflectors that have a compatible fan mount (four M4 x 0.7 threaded holes in a square pattern with holes spaced 71.5mm apart).
