Condition:
This is a used C6 OTA that is in good condition. The optics are relatively clean. There seems to be some dust on the inside of the corrector plate and the body has a couple of minor marks that can be seen in the provided photos. This also includes a Celestron star diagonal.
Because the body and optics are not in pristine condition, we have discounted the price heavily off of the new unit. Save big at almost HALF-PRICE!
