Please Note: All Sharpstar 61EDPH refractors undergo physical, mechanical and optical QC inspections at the factory, and an inspection checklist is included with each telescope (for an example of this certificate, please see the last photo above). We (Agena) partially open the scope boxes to ensure that the scope has been inspected/certified by Sharpstar but we do not open the scope and inspect it again. If you would like us to inspect your telescope again before we ship it, just request this in the comments field when you place your order. We will be happy to do this at no extra cost for this scope, but this will delay your shipment by 2-3 business days.
