Baader Planetarium Star Diagonal

The T-2 system allows for a modular setup, meaning you can adapt the diagonal to various telescope systems and imaging trains without the limitations of fixed-barrel designs. It gives you the flexibility to swap components or add accessories without creating bottlenecks in your optical path.

The diagonal features a 32mm clear aperture, which is quite generous for a 1.25-inch system. This design is specifically engineered to minimize vignetting, ensuring you get a clear, unobstructed view even with wide-field eyepieces.

Yes, it is designed with a standard 1.25-inch barrel on both the telescope and eyepiece sides, making it universally compatible with any focuser or eyepiece that accepts the standard 1.25-inch format.

This diagonal is built for users who want to customize their optical train. If you are just doing basic visual observing, a standard diagonal is fine, but if you plan on adding cameras, filter wheels, or specific adapters, the T-2 system provides the structural versatility that standard diagonals lack.

Yes, like all standard 90-degree star diagonals, this will provide an upright but mirror-reversed image. This is standard for astronomical viewing, as orientation is generally not critical when observing celestial objects.
