  • Nice Telescope

    from Halifax NS on June 27, 2015

    I purchased this telescope for myself a couple weeks ago. It was a great purchase. The telescope works perfectly and i could see very nice close ups of the moon and some planets. I could see Saturn and Jupiter with its moons no problem without even using the magnifier. I recommend this to anybody looking to buy their first telescope.
