## Description

This 90-degree star diagonal makes visual observing more comfortable by redirecting the eyepiece to a convenient angle for prolonged sessions at the eyepiece. It is suited to telescopes with 1.25 inch focusers and accepts standard 1.25 inch eyepieces, allowing easier viewing of planets and lunar detail from a more ergonomic position. 😊

## Key Points

The diagonal presents images correctly oriented vertically while reversed left to right, which can simplify terrestrial viewing and still work well for astronomical observation. It accepts 1.25 inch oculars and common accessories such as Barlow lenses and extension tubes, so it integrates smoothly with many beginner and intermediate setups. According to the manufacturer, the unit is finished in black and includes a two year warranty with technical support from Celestron. Consider that the left-right reversal is normal for a 90 degree star diagonal and may affect applications where true mirror orientation is required. 🔭

## Benefits

Using a 90° diagonal reduces neck strain during extended observing by allowing the eyepiece to be viewed at a comfortable angle when the telescope is pointed high in the sky. The compatibility with standard 1.25 inch eyepieces and accessories means you can use your current ocular collection without extra adapters. For casual planetary viewing and lunar sessions, the diagonal keeps sessions more relaxed and focused on detail rather than on awkward body positioning. Also, the black finish minimises stray reflection inside the optical train.

## Usage Recommendations

Attach the diagonal to any telescope focuser designed for 1.25 inch accessories, tightening the thumbscrews gently to avoid stress on the focuser or the diagonal tube. When switching between oculars and Barlow lenses, support the eyepiece to prevent flexing or accidental drops. For terrestrial use, be mindful that the image will be laterally reversed, and for applications that require true left-right orientation a different diagonal type would be more appropriate. 😊
