ZWO FF80 APO OTA

The ZWO FF80 APO is a flat field astrograph that can be used visually as well. Its design negates the need to calculate the back focus distance from the flattener while attaching all your imaging gear. You should be able to connect a reasonable amount of equipment and start imaging. This should help with the frustration of getting everything just right and simply let you enjoy your imaging session. You can use a variety of diagonals for visual observation should you choose to look through your telescope and not just image through your telescope. The telescope is fairly compact and lightweight. The ZWO FF80 is a hair under 18" long and weighs in at 10.3 pounds with rings and dovetail. The 80mm aperture scope uses a dual ED quadruplet optical system to help achieve its flat field. It has an f/7.5 native f ratio, but can be made faster with optional .76x Reducer further reducing the speed as well as the 600mm native focal length to f/5.7 and 456mm. The ZWO FF80 can support a 44mm image circle allowing it to be used with full frame cameras. The 3" rack and pinion focuser has a built in camera rotator and finder shoe for Vixen style finder brackets. The telescope comes with M76, M68, M54m and M48 Camera adapters and the M48 is threaded for filter.
