Product details
This apochromatic refractor is based on a triplet with a central Ohara FPL-53 fluorite element. All lenses are blackened at the edges and FMC-coated. The enclosed optical measurement report shows a Strehl ratio of at least 0.95!
The aluminium tube is equipped with stray light baffles. The retractable dew shield ensures compact transport dimensions and has a locking knob.
The generously sized drawtube illuminates full-frame cameras and provides precise focusing with 1:10 reduction. Using the integrated field rotator, the camera can be rotated into the desired position in order to find the best field of view. The focuser takes 2” attachments using a self-centering locking system. The same system is also built into the adapter for 1.25” attachments. This means that accessories can be clamped in the precise centre, even when wearing thick gloves!
The newly-designed pipe brackets allow the use of Vixen- and Losmandy-style prism rails. A comfortable grip, ideally suited to attaching additional accessories, such as guidescopes, is located above the rings.
For photographic use, Tecnosky offers an optional 0.8x flattener/reducer, with which the apochromat can achieve a fast aperture ratio of f/4.8.
A sturdy case is included.
