Explore 56 SAP
The Sky Rover 56SAP pairs a 56 mm aperture with a fast f/4.8 Petzval optical system for wide-field astrophotography. Its native flat field is designed to support full-frame imaging without a separate field flattener. At 269 mm focal length, it offers a compact format for expansive views of nebulae and star fields.
56 mm f/4.8 quintuplet Petzval astrograph
Native flat field with a 45 mm image circle for full-frame imaging
Helical focuser with 27 mm effective travel
Integrated tilt adjustment and camera rotation
CNC-machined aluminium alloy tube with dew shield
The quintuplet Petzval design produces a native flat field with a 45 mm image circle, supporting full-frame imaging. Because field flattening is built into the optical design, a separate flattener is not needed, avoiding the flattener-to-sensor spacing requirements typical of many astrophotography refractors.
A broad, ribbed helical ring integrated into the telescope body provides manual focus control, with 27 mm of effective focuser travel. Its compact, manual design keeps focusing straightforward, but it is distinct from a powered focuser.
A rear rotation mechanism with an angular scale lets you adjust camera orientation without rotating the whole telescope assembly. Integrated tilt adjustment provides another way to adjust the camera position, without implying a particular correction or result.
The camera interface is listed as M54 x 0.75 / M48 x 0.75. Before connecting your camera, check its connection and verify whether your setup requires an adapter.
The package lists tube rings, a Vixen-style dovetail plate, carry handle, dual finder bases, soft carry bag and electronic focuser mounting kit, alongside the OTA. The OTA weighs 2.3 kg. Its listed length is 251 mm with the dew shield reversed or 326 mm with it attached. The separately stated gross weight with tube ring and dovetail is 2.7 kg.
