Questions & Answers

  • What type of GOTO or EQ motorized mount works for this telescope?

    Hi Alexandra,
    I would recommend an HEQ5 minimum for the scope as it's a 22lb OTA, and you will want to add a few pounds of extra equipment.  
    An AVX mount would be borderline overloaded, if you go with Celestron, I would go with a CGEM II mount.
