Flatfield APO refractor telescopes from 30 mm to 151 mm Aperture - specialists for astrophotography.

The image of these apos is flat and die color aberation is well corrected. Astrophotographers prefer this telescope type because of the simple and effective adaption. No additional corrector is needed.

The refractors of TS Optics are our suggestion. Superb quality for imaging and also good for visual at an affordable price. These Apos are the alternative to expensive telescopes but with similar quality.
