## Long description

Skywatcher SWA-58 9 mm eyepiece with a 1.25" barrel and a 58° apparent field is designed for visual astronomy with compatible telescopes. It provides a moderate level of magnification suitable for detailed views of the Moon and planets while maintaining a relatively wide apparent field that helps track objects and frame extended deep-sky targets. The eyepiece fits standard 1.25" focusers and is intended for observers who need a balance between magnification and usable field of view.
Advantages
The 9 mm focal length delivers increased magnification compared with low-power eyepieces while the 58° apparent field provides a comfortable viewing circle without excessive eye positioning constraints. The 1.25" barrel format ensures broad compatibility with most amateur telescopes and accessories. Optical correction in the SWA-58 design reduces coma and edge aberrations typical in simple eyepieces, offering improved sharpness across much of the field.
Suitable for
 Planetary observation (Moon, Mars, Jupiter, Saturn)
 Lunar detail studies and crater observation
 Medium magnification views of smaller deep-sky objects (compact nebulae, globular clusters)
 Visual observing sessions with 1.25" focusers
Key specifications
 Focal length: 9 mm
 Apparent field of view: 58°
 Barrel diameter: 1.25 inches
 Optical design: multi-element SWA configuration for improved edge performance
 Typical use: visual astronomy with refractors, reflectors, and catadioptric telescopes that accept 1.25" eyepieces
How to use
Insert the eyepiece into a clean 1.25" focuser and secure it using the focuser’s set-screw or compression ring. Start with low magnification to locate the target, then switch to the 9 mm eyepiece for increased detail. Allow your eyes a minute to adapt to darkness for best contrast. For highest image quality, ensure the telescope is collimated and cooled to ambient temperature; if using a Barlow lens or diagonal, confirm backfocus compatibility before observing.
Usage recommendations
Use the SWA-58 9 mm eyepiece under steady atmospheric conditions for best planetary detail. For extended deep-sky objects, pair it with a lower-power eyepiece to frame the target, then return to the 9 mm for focused study. Store the eyepiece in a protective case and clean optical surfaces with appropriate tools only when necessary.
