Description
To achieve the sharpestviews faster, we recommend pairing the StarSense Explorer 12 Dobsonian with the USB Cooling Fan for Dobsonian Telescopes (sold separately). The fan cools the primary mirror to the ambient outdoor temperature faster, leaving you more time to observe. It mounts directly onto the rear cell of the Dobsonian and works with any USB power source.
