ZWO FF130 APO Telescope

The ZWO FF130APO is a refractive astrograph with a powerful flatfield optical design which saves you from the expensive cost of a field flattener. It eliminates the trouble of calculating the back focus distance of the flattener and connecting various accessories to achieve that distance. You can just connect any possible accessories you need. As long as the target is focused, the whole optical system is perfect for imaging. This makes the whole setting up process much more convenient, and saves you time, allowing you to pay more attention to the image shooting itself.

Compared to the ZWO FF107 APO, the ZWO FF130 APO has a larger size. The aperture is 23mm larger. The focal length at f7/7 is also longer, this will yield higher details and slightly higher magnifications but with a field of view suitable for all deep-ky objects. The longer focal length will be especially effective on planetary and larger deep-sky objects which, when combined with the larger 130mm aperture, will provide stunning details in a reasonable time.

The ZWO FF130 APO with its quadruplet lens structure which contains two pieces of ED glass will control chromatic and other aberrations. With its self-flattening design, the ZWO FF130 APO offers strong advantages in astronomical shooting. It supports a medium frame 60mm image circle, has a fine spot diagram with tiny distortion on the peripheral stars, and its central RMS radius is less than 2 microns.

The OTA weighs only 10.5 kg, and the full package with tube rings and other accessories weighs 12.5kg. The 3.4″ rigid focuser comes with a new-type 360°rotator with scales and a finder base. M86, M68, M54, and M48 camera adapters are also attached, and the M48 adapter has a 2” female thread for installing filters. When used with the 3" 0.7x flat-field reducer, the telescope can reach a focal ratio of f/5.4 and a focal length of 700mm, effectively reducing exposure time. The Multifunctional handle comes with a central slot for attaching an M6 screw with an M6 screw hole. standard KLOsmandy dovetail plate, together with sturdy double rings. It is perfectly suitable for viewing and shooting.
