## Summary description

Skywatcher Evoguide 50 (model SW-5414) is a field flattener designed for 50 mm refractor telescopes. It corrects field curvature to deliver sharper stars across the imaging field, improving edge-to-edge sharpness for astrophotography. Compatible with Evoguide series, it mounts between the telescope and camera or eyepiece, helping achieve flatter, more usable frames for wide-field deep-sky and planetary imaging.

## Long description

Skywatcher Evoguide 50 SW-5414 is a field flattener engineered for 50 mm refractor telescopes. It reduces field curvature and improves point-source sharpness across the imaging circle, making stars appear sharper from centre to edge. The flattener fits between the telescope's focuser and the camera or eyepiece and is compatible with the Evoguide series optical train. It is intended for wide-field astrophotography where edge sharpness and uniform star images are required.
Advantages
The Skywatcher Evoguide 50 delivers a flatter focal plane and better edge-to-edge sharpness compared with plain refractor optics, reducing star elongation and coma at the frame borders. Its optical design preserves contrast and minimizes additional aberrations when used within the specified backfocus range. Mechanical mounting is straightforward for standard 50 mm guide scopes and dedicated Evoguide accessories, allowing reliable repeatable connection between telescope and imaging device.
Suitable for
 Wide-field deep-sky imaging with 50 mm refractors
 Planetary and lunar imaging where uniform star points are desired
 Guide-scope setups in small refractor imaging trains
 Astrophotographers seeking improved edge-to-edge star sharpness
Key specifications
 Optical purpose: field flattener for 50 mm refractor telescopes
 Compatible telescope aperture: 50 mm guide and refractor tubes
 Designed mounting position: between focuser and camera/eyepiece
 Effect: corrects field curvature to improve edge sharpness
 Application: wide-field astrophotography and guiding
How to use
Install the flattener directly into the focuser or adapter designed for the Evoguide series, then attach the camera or eyepiece to the flattener's output. Ensure the optical spacing (backfocus) recommended for the Evoguide 50 is observed to achieve the intended field flattening; adjust the camera's position along the imaging train until stars are round across the frame. Balance and collimate the telescope as required for your imaging setup and perform usual focus and framing adjustments before starting exposures.
Usage recommendations
For best results, verify the mechanical spacing between the flattener and camera sensor according to Skywatcher Evoguide guidance, use software-assisted focusing and check stars at the frame corners during initial setup. When combining with additional adapters or extension tubes, test and re-check field sharpness and re-focus as necessary.
