ZWO FF110 f/7 APO REFRACTOR

The ZWO FF110 is an apochromatic quadruplet flat-field astrograph that offers high performance for an exceptionally low price. The quadruplet design makes it perfect for both visual observation and astrophotography. The objective lens features an element of extra-low dispersion glass (ED) that minimizes chromatic aberration. 

The ZWO FF110 is a versatile instrument and excels not just at imaging, but as a grab & go visual telescope (eyepieces & diagonal sold separately).

Unlike traditional refractors, the quadruplet design does not require a separate field flattener and you do not need to calculate precise backfocus. With a large image circle of 44mm, the ZWO FF110 is a highly capable imaging telescope.

The OTA itself weighs just 5.74kg (6.76kg with tube rings and dovetail bar) and has an overall length of 664mm with the dew shield contracted, making it easy to transport.

The 3" dual-speed rack & pinion focuser is precise and rigid. It is natively compatible with most motorized focusers on the market including the ZWO EAF. The focuser includes 2" and 1.25" visual adapters as well as M48 and M54 camera adapters. On the rear there is a 360 degree rotator with fine rotation angle markings for precise framing. A 2" mounted filter can be attached to the rear M48 camera adapter.

Unlike most refractors, the FF110 includes two finderscope bases on either side of the focuser, allowing you to attach both a standard guide scope and control unit such as the ASIAIR without the need for additional accessories. The handlebar also includes a finder-style slot, allowing for even more possibilities.
