Not Returnable Please note that used items are not returnable.

Condition: This is a used C6 OTA off of a 6SE that is in good condition.  The optics are relatively clean.  There is a tiny dot on the corrector plate that we cannot remove; there is also some circular streaking near the secondary and at the edge where the previous owner tried to clean the corrector plate.  See the photos; the dot is between 3 and 4 o'clock, about an inch to the right of the secondary.

This streaking is extremely minor, and will not affect your views. However, because the optics are not in pristine condition, we have discounted the price heavily off of the new unit.  Save big at almost HALF-PRICE!  

The body is unmarked. It includes the an RDF, a 1.25'' diagonal, and a 25mm Plossl.  We can ship this to you.
