Teleskop Service sets with the PHOTOLINE APO series uncompromising optical and mechanical quality.
This apochromatic refractor is equipped with one of the best lenses in its class. The moderate aperture ratio and the use of two special lenses (FPL53 and Lanthanglas) allows for a correction that is clearly visible above the level of the two-lingual ED apos in this price range. The picture is similar to three-lensed lenses. The telescope is fully usable visually and thanks to the optional field flattener and focal length reducer, nothing stands in the way of astrophotography.
