Questar field model. Pristine secondary and mirror. Two eyepieces, Brandon, screw in type... 40-80X, and 80-160X using built in barlow lens. A camera adapter is included. Crisp, clear views. Scope is perfect except for some areas of discoloration at the rear (see pic); I have priced it accordingly $300 - 500 below what these scopes usually sell for on the 'Mart.
