Cool down the primary mirror of your Celestron StarSense Explorer 10" Dobsonian telescope with this "cool" accessory, the Celestron USB Cooling Fan!  Once you match the temperature inside your telescope's optical tube to the outside ambient temperature, you'll get crisper, better-focused results.  This fan is especially nice for telescopes that are stored inside, where there may be a big difference between indoor and outdoor temperatures.

The USB Cooling Fan for Dobsonian Telescopes mounts directly onto the rear cell of the StarSense Explorer 10” Dobsonian telescope, but it also works great with 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).

This cooling fan works with any USB power source (portable power banks, AC wall adapters, and more).  Once the primary mirror has cooled down and you are ready to observe, you can disconnect the fan’s USB power source. Connect the cable to the integrated storage clip to stay organized.
