repair or replace such product or part thereof which, upon inspection by CI, is found to be defective in materials or
workmanship. As a condition to the obligation of CI to repair or replace such product, the product must be returned to CI
together with proof-of-purchase satisfactory to CI.

B.

The Proper Return Authorization Number must be obtained from CI in advance of return.  Call Celestron at (310) 328-9560 to
receive the number to be displayed on the outside of your shipping container.

All returns must be accompanied by a written statement setting forth the name, address, and daytime telephone number of the
owner, together with a brief description of any claimed defects.  Parts or product for which replacement is made shall become
the property of CI.

The customer shall be responsible for all costs of transportation and insurance, both to and from the factory of CI, and
shall be required to prepay such costs.

CI shall use reasonable efforts to repair or replace any telescope covered by this warranty within thirty days of receipt. In the
event repair or replacement shall require more than thirty days, CI shall notify the customer accordingly.  CI reserves the right to
replace any product which has been discontinued from its product line with a new product of comparable value and function.

This warranty shall be void and of no force of effect in the event a covered product has been modified in design or
function, or subjected to abuse, misuse, mishandling or unauthorized repair.  Further, product malfunction or
deterioration due to normal wear is not covered by this warranty.

CI DISCLAIMS ANY WARRANTIES, EXPRESS OR IMPLIED, WHETHER OF MERCHANTABILITY OF FITNESS FOR
A PARTICULAR USE, EXCEPT AS EXPRESSLY SET FORTH HEREIN.

THE SOLE OBLIGATION OF CI UNDER THIS LIMITED WARRANTY SHALL BE TO REPAIR OR REPLACE THE
COVERED PRODUCT, IN ACCORDANCE WITH THE TERMS SET FORTH HEREIN.  CI EXPRESSLY DISCLAIMS
ANY LOST PROFITS, GENERAL, SPECIAL, INDIRECT OR CONSEQUENTIAL DAMAGES WHICH MAY RESULT
FROM BREACH OF ANY WARRANTY, OR ARISING OUT OF THE USE OR INABILITY TO USE ANY CI PRODUCT.
ANY WARRANTIES WHICH ARE IMPLIED AND WHICH CANNOT BE DISCLAIMED SHALL BE LIMITED IN
DURATION TO A TERM OF ONE YEAR FROM THE DATE OF ORIGINAL RETAIL PURCHASE.

Some states do not allow the exclusion or limitation of incidental or consequential damages or limitation on how long an
implied warranty lasts, so the above limitations and exclusions may not apply to you.

This warranty gives you specific legal rights, and you may also have other rights which vary from state to state.

CI reserves the right to modify or discontinue, without prior notice to you, any model or style telescope.
