William Optics Durabright Diagonal

Yes, this diagonal is specifically designed for SCTs. It attaches directly to the standard SCT visual back, providing a secure and stable connection for your setup.

The 1/10th wave accuracy refers to the precision of the mirror's surface flatness. This high level of precision ensures that the light path remains undistorted, resulting in sharper, more detailed views of planets and the moon compared to standard diagonals.

No, the compression rings are designed to protect your equipment. Unlike traditional thumbscrews that can scratch or mar the barrel of your eyepiece, the brass compression ring applies even pressure to hold the eyepiece securely in place without leaving marks.

Yes, the diagonal comes with a 2-inch to 1.25-inch adapter. This allows you to use your larger 2-inch eyepieces for wide-field views or switch to your 1.25-inch eyepieces using the included adapter.

Absolutely. The internal anti-reflection baffling is designed to suppress stray light that can bounce around inside the diagonal housing. By minimizing these reflections, you get better contrast and a darker background, which is crucial for viewing faint deep-sky objects.

No, this unit is designed to maintain constant alignment right out of the box. You do not need to perform any manual adjustments to the mirror, making it a reliable, 'set-it-and-forget-it' upgrade for your telescope.
