30-day return policy. With exceptions noted below, Protostar products can be returned for any reason within the first 30-days. The product may be returned for replacement, repair, or refund (your choice). Special exceptions are:
Telescope tubes and tube liners that have been drilled or cut by the customer, or cut to a custom length by us, cannot be returned except in case of a defect.
Straight-vane secondary mounts (i.e., "spiders") cannot be returned because of wrong sizing if we were provided with an incorrect tube ID. In many cases we can modify your spider to a new dimension for a small fee.
Secondary mirrors must be returned in "like new" condition.
One-year limited warranty. In addition to the 30-day return policy, Protostar products are warranted against defects in material and workmanship for one year after the shipping date. Defective products will be repaired or replaced if they are out of the 30-day warranty period. The warranty does not cover normal wear, damage, or loss, and is void if the unit is modified from the original design or disassembled beyond the intent of the design.
