## Summary description

Focal reducer designed for the Skywatcher Evostar 72ED 0.85x to shorten focal length by 15% and improve field of view. Intended for use with compatible Evostar 72ED refractor telescopes, it helps expand the observable sky area, reduce exposure times in astrophotography, and produce wider field images with reduced focal ratio. Simple to install between telescope and camera or eyepiece, it is practical for wide-field visual observing and imaging.

## Long description

Focal reducer for Skywatcher Evostar 72ED 0.85x is a dedicated optical accessory designed to shorten the focal length of compatible Evostar 72ED refractor telescopes by approximately 15%. Installed between the telescope and the camera or eyepiece, this reducer lowers the effective focal ratio, widens the field of view and reduces required exposure times for imaging. The unit is intended specifically for use with Skywatcher Evostar 72ED 72 mm ED refractors and provides a practical way to capture wider sky areas while maintaining the telescope's optical performance.
Advantages
The reducer decreases the focal length and focal ratio uniformly across the field, making full-frame and APS-C sensor coverage more practical for wide-field astrophotography. It enables shorter exposure times and broader framing without requiring a different objective or complex modification of the telescope. The mechanical interface is designed for straightforward placement between the telescope drawtube and camera or visual eyepiece, allowing quick installation and removal for visual observing or imaging sessions.
Suitable for
 Wide-field astrophotography with Skywatcher Evostar 72ED refractors
 Reducing exposure times for deep-sky imaging on small telescopes
 Visual observing when a wider field of view is desired
 Use with DSLR, mirrorless cameras or dedicated astronomy cameras
Key specifications
 Reduction factor: 0.85x (approximately 15% shorter focal length)
 Compatibility: designed for Skywatcher Evostar 72ED refractor telescopes
 Optical role: focal reducer to lower effective focal ratio for wider field
 Mounting: inline placement between telescope drawtube and camera or eyepiece
 Intended use: wide-field imaging and visual observation with reduced focal ratio
How to use
To use the focal reducer, remove any existing visual back or extension and insert the reducer into the telescope drawtube following the manufacturer’s mounting orientation. Attach the camera or eyepiece to the reducer’s output connection and verify secure mechanical coupling. After installation, adjust focus on the camera or eyepiece as the focal plane shifts due to the reduced focal length. For photographic use, reframe and refocus using live view or short test exposures before committing to long exposures. For visual use, perform minor focus adjustments at the eyepiece to achieve a sharp image across the field.
Usage recommendations
Use the reducer specifically with the Skywatcher Evostar 72ED optical tube to ensure optimal image quality. Check backfocus and spacing between the reducer and camera sensor or eyepiece to achieve proper focus and minimize field curvature. For best photographic results, verify collimation and ensure stable mounting; short exposures are often sufficient for bright deep-sky targets when using the reducer. Avoid forcing incompatible adapters—confirm thread sizes and mechanical fit before use.
