IOPTRON 1.25" ERECT PRISM DIAGONAL
For terrestrial viewing (birds, landscapes, etc), it is preferred to view objects in their correct orientation. Rather than using a star diagonal that will flip the image, the erect prism diagonal corrects the image upright and from left to right, while placing the eyepiece at a comfortable 45-degree viewing angle. It will fit most 1.25" focusers and will accept eyepieces with 1.25" barrels.
