This ZWO package combines the FF90 flat-field apochromatic refractor, AM3N strain-wave mount, PE160 pier extension and TC40 carbon-fibre tripod. Manufacturer bundle variants list these four named components together.
The FF90 uses a four-element air-spaced APO objective with one ED element. Its 90 mm aperture and 609 mm focal length give f/6.8, with a 44 mm image circle and no separate external field flattener required. The 3-inch rack-and-pinion focuser has 1:10 fine adjustment and a 360° camera rotator.
The manufacturer imaging focus range is 45–75 mm from M54–M48 shoulder. Maximum optical paths are 75 mm at M48 and 93 mm at M54; use the reference shoulder specified in the manufacturer diagram. The tube weighs 3.92 kg, or 4.52 kg with handle, rings and dovetail plate. Retracted/extended visual and imaging lengths are listed below.
The AM3N offers equatorial and alt-azimuth modes with 8 kg without counterweight; 13 kg with counterweight. Its body weighs 4.1 kg, the saddle accepts Vixen and Losmandy plates, and latitude adjustment spans 0–90°. Use 12 V DC, at least 3 A; 5.5 × 2.1 mm centre positive. USB, Wi-Fi, Bluetooth and ST4 connections support the documented control options.
The PE160 provides elevation between mount and tripod. Its approximately 1 kg structure has a manufacturer recommendation below 10 kg; that restriction still applies even if the mount is counterweighted for a higher payload. The TC40 weighs 2.3 kg, adjusts from 470 to 800 mm and has 40/36 mm two-section carbon-fibre legs with a ballast bag. Its 50 kg structural rating is separate from the imaging payload of the mount.
Telescope, camera, filter wheel, adapters and cables all contribute to the imaging load and clearance envelope. Follow the mount’s counterweight and lever-arm guidance and use the lowest applicable component limit. A camera and any optional reducer, filters or counterweight are separate from the four components named in this package.
