Aaaaah...Warmth!In far-northern or far-southern climes it can get pretty cold when you're waiting for your telescope to cool or that star to appear. Other than a warm fire nothing's handier at such times than an Exotherm reusable handwarmer. Celestron's version provides an hour's worth of heat to thaw frigid fingers so you can manipulate the focus knob when you need to. It's perfect for those long winter nights in the field when you just can't wait for summer.Find your way around the night sky with Celestron Sky Maps.
