To begin, please view the original message sent to when you joined the Sky & Telescope Zenith Club, as it contains links attached to unique promotional codes for your account, and will guide you in either creating an account (if you are not currently an iTelescope  member) or activating your special benefits (if you are currently an iTelescope member).  Once you have fully activated your Zenith Club iTelescope membership, you can check our Getting Started - iTelescopes Basics FAQ Section, where you will find answers and advice for all things iTelescope.  As always, we are also happy to assist if you via email at support@itelescope.net.
