Orion 1.25-Inch Mirror Star Diagonal 

 Many observers prefer to use a good-quality mirror diagonal instead of a prism diagonal with their telescope systems. Consider the Orion Mirror Star diagonal! The mirror in this 90-degree diagonal is meticulously polished to yield maximum performance. The housing is made of black-anodized aluminum, and the barrel is internally blackened. 

The Orion Mirror Star Diagonal renders images that are right-side up and reversed left to right (therefore, not recommended for terrestrial observing). Diagonals are not recommended for use in reflector telescopes.
