Omegon Premium Flatfield 10,5 mm Oculair 60° (1,25 inch): vlak beeldveld met ED-optiek
Het Omegon Premium Flatfield 10,5 mm doet wat de naam belooft: een vlak beeldveld waarin sterren ook aan de rand puntvormig blijven. De planeet-allrounder van de serie met een middelhoge vergroting.
The series corrects the field curvature that makes most eyepieces blurry at the edge, and the ED lens element keeps the color reproduction pure. Even on fast Newtons around f/5, the edge remains sharp.
Flat field, high contrast
The optical construction with an ED element and multi-layer coating on all air-to-glass transitions delivers a sharp image with high contrast. Objects that drift to the edge retain their shape and sharpness.
Pleasant insight, parfocal series
With an interpupillary distance of 16 mm, you can observe relaxedly, without black shadows if your eye is slightly off-axis. The series is parfocal: changing the focal length requires hardly any refocusing.
The 1.25-inch barrel has filter threads for moon and color filters.
Wat zie je met 10,5 mm?
Op een telescoop met 900 mm brandpuntsafstand geeft 10,5 mm een vergroting van 86x, op een 200/1200 Dobson 114x. De wolkenbanden van Jupiter en de ringen van Saturnus komen goed door.
Ook bolvormige sterrenhopen tonen hun korrelige structuur tegen een strak veld.
Featured accessories
The Premium Flatfield series ranges from 5.5 to 25mm and is parfocal: two or three focal lengths form a complete set. An Omegon moon filter (1.25 inch) dims the bright moon image at longer focal lengths.
For whom yes and for whom no
- ✓ Observers with fast telescopes (f/5) who value edge sharpness
- ✓ To see stars as pinpoints to the edge instead of smeared
- ✓ Owners of multiple focal planes in the series: parfocal switching
- For those seeking the widest field of view: the SWA and Redline series offer 70 degrees
- ✗ Smart telescopes without interchangeable eyepieces
