Astronomy Plus 1.25" Erect Image Prism Diagonal
An erect image diagonal corrects the image orientation, making it appear right-side up and correctly oriented left to right, unlike standard diagonals that produce a mirrored or inverted view. This makes it especially useful for daytime terrestrial observations, such as wildlife or landscape viewing, where a natural image orientation is essential.
This machined 90 degrees diagonal suits most refractors that accept 1.25" accessories, making it a versatile upgrade for improved ergonomics and image clarity. By using a high-quality prism, it ensures minimal light loss and delivers sharp, well-contrasted views of celestial objects.
The barrel is threaded, allowing compatibility with standard 1.25" filters for enhanced viewing and imaging versatility.
