TS-Optics Premium Flat Field Eyepieces

These eyepieces convince by a very good insight with good image field correction at the same time. The eyepieces offer high observation comfort and are well suited for beginners and also for advanced users. The good field correction is maintained even with fast optics.
 

Applications of the TS Premium Flatfield Eyepieces:

♦ Deep sky observation - the high transmission allows to use the aperture of the telescope well.
♦ Lunar and planetary observing - clean inner blackening provides high contrast.
♦ Double star observing - even if the fainter component is close to the main star, it will be detectable if the resolution of the telescope allows it.
♦ Binocular observation - the comfortable view also allows binocular observation.
♦ Astrophotography - eyepiece projection - the narrow design of the eyepieces allows the use with eyepiece projection adapters.
