Telescope Astrógrafo Cuadruplete ZWO FF130 APO

The FF130 includes two Extra Low Dispersion glass elements for superb chromatic aberration correction. The FF130 is compatible with medium format cameras such as the ASI461MM Pro, with an RMS center radius of only 2 microns.

Unlike standard ED refractors, the FF130 features a Petzval design that does not require the sensor to be set at a specific distance from the last lens. This leaves the freedom to use any filter wheel, any off-axis guide or accessory without worrying about calculating the correct distance from the flattener.

With a large 60mm image circle and a focal ratio of f/7.7, this is the perfect astrophotographer for the advanced astrophotographer.

The large 3.4" rack and pinion focuser is natively compatible with the ZWO EAF without the need for additional adapters, and can be rotated 360° to perfectly frame the subject and has a 10:1 reduction gear for precise focusing.
