Tecnosky 90/540 mm FPL55 Apochromat, OWL Series

This apochromatic refractor features a triplet objective with central Ohara FPL55 fluoride glass element. All lenses are blackened at the edges and FMC coated. The supplied optical measurement report shows a Strehl of min. 0.95!

The aluminum tube is equipped with lens hoods. The retractable dew shield makes the apo very transportable and even has room in airplane luggage.

The generously sized focuser illuminates full-frame cameras and allows precise focusing with 1:10 dual speed. The integrated field rotator allows the camera to be rotated to the desired orientation for best framing. The 2" and 1.25" accessories are clamped gently. In addition, the focuser offers an auxiliary thread for screw adaptations.

Included is a dovetail bar (Vixen style). Other dovetails can be connected, including Losmandy style ones. A carrying handle allows convenient transport and also mounting of accessories such as guiding scopes.

For photographic use, Tecnosky offers an optional 0.8x flattener/reducer that gives the apochromat a fast focal ratio of f/4.8.
