Omegon SWA 10mm 70° 1.25″ eyepiece
If you are looking for an eyepiece that opens up the universe in all its splendour, the Omegon SWA series is exactly what you need. The SWA 10mm with a 10mm focal length and a 70° apparent field of view belongs to a new generation of wide-angle eyepieces that clearly surpass their predecessors in both optical design and ergonomics. Get ready for an unforgettable feeling of immersion in deep space - without constantly shifting your gaze across the field of view.
Optical design and image quality
The optical system consists of five optical elements arranged in three or four groups depending on the focal length. All glass elements feature a modern broadband FMC (Full Multi-Coating) layer, which significantly increases light transmission and minimises unwanted reflections. The lens edges are blackened, which effectively suppresses internal light scatter and ghost glare - the result is a highly contrasty and sharp image that demanding observers expect. The Omegon SWA 10mm eyepiece delivers performance that will be appreciated by experienced astrophotographers and visual deep-sky observers alike.
Ergonomics and build quality
The designers paid great attention to ergonomics. The eyepiece body is almost completely rubber-coated, so it sits comfortably in the hand even on cold nights. The new adjustable eye cup ensures comfortable eye placement and helps maintain the correct eye relief without unnecessary effort. The overall design is robust and practical - the eyepiece will easily find a place in any observing bag.
Parfocal series - change eyepieces without refocusing
The Omegon SWA series supports parfocality - which means that when swapping one eyepiece for another within the series, you do not need to refocus your telescope. This seemingly small feature proves enormously practical during serious observing sessions. Omegon SWA wide-angle eyepieces are available in the following focal lengths and barrel sizes:
| Focal length |
Barrel size |
| 10mm |
1.25″ |
| 15mm |
1.25″ |
| 26mm |
2″ |
| 32mm |
2″ |
| 38mm |
2″ |
This makes it possible to build a complete parfocal set for every situation - from high magnifications to wide overview fields.
