This is a CPC 1100 in only fair to good shape. The optics are fine; it's the tripod that isn't looking so good.  The previous owner was from Houston, and stored this under a tarp in his garage.  The humidity there got to the tripod legs and created rust spots all over them, as well as to other exposed untreated metal, such as the accessory screws around the tube.  See the photos.  However, this rust is cosmetic only.  The tripod still functions as it should; the accessory screws still screw in and out and hold accessories in place.  

On the other hand, the telescope's optics are in excellent condition.  The corrector plate is clean; there are two tiny marks on the primary mirror, only a couple of millimeters in length each.  These will not affect your views.  (In the photo, one is at 4 o'clock on the inside edge; the other is at 8 o'clock on the outside edge.)  

This scope is 8 years old, originally purchased in 2015.  It has full StarBright XLT coatings, and is complete with its original accessories, plus AC Adapter. 

We've taken these condition issues into the pricing of this item.  If you've been looking for a CPC 1100, this is an incredible bargain at well over half-off the new price. 

This is for local pickup only, as we do not have any shipping boxes for this item.
