Meade Customer Service

If you have a question concerning your Meade Starfinder
telescope, call Meade Instruments/Customer Service Dept. at
949-451-1450, or fax at 949-451-1460. Customer Service hours
are 8:30AM - 4:00PM, Pacific Time, Monday through Friday. In
the unlikely event that your 16" Starfinder telescope requires
factory servicing or repairs, write or call the Meade Customer
Service Dept. first, before returning the telescope to the factory,
giving full particulars as to the nature of the problem, as well as
your name, address, and daytime telephone number. The great
majority of 16" Starfinder servicing issues can be resolved by
telephone, avoiding return of the telescope to the factory.
