Availability: Available



Manufactured by: Bresser


The Bresser Messier AR-102/1000 Refractor OTA is capable of showing many details in celestial objects like Saturn's rings, Jupiter's cloud bands as well as craters on the moon. With a two-element air spaced crown objective, the anti-reflecting coatings result in very sharp detailed views, therefore enhancing light and dark comparisons. For even better contrast, the observer can use the attached dew shield installed. A few accessories are also included. Bresser has included a 2" rack and pinion focuser with the purchase of this telescope that assists in repeatable focusing and includes brass compression rings to not scar or damage eyepiece or other accessory barrels. Other accessories included are a 2" diagonal as well as a 25mm 70° 2" eyepiece. If the observer wants to use 1.25" eyepieces, the focuser has an adapter. For astrophotographers, the carry handle is capable of mounting a DSLR camera for exposures.
