This is a used Explore Scientific 127mm FCD100 APO refractor in good condition.  There are some minor spots and a streak on the back of the front objective lens that we cannot clean.  See the photos.  This should not affect your views.  Otherwise, the body is clean and unmarked.  The lens condition has been taken into consideration in the pricing.  This is an incredible savings at less than one-third of the new price.  

Includes the original Explore Scientific dielectric 99% reflective diagonal.  


We do not have the original shipping box for this, so this is in-store pickup only.
