Description

Precision ED optics define the Levenhuk AP 72/432 ED FT72 Ra OTA, an apochromatic refractor with a 72 mm aperture, 432 mm focal length, and listed f/6 optical ratio. Its ED doublet objective, fully multi-coated optics, 2-inch Starlight Instruments Feather Touch focuser with 10:1 adjustment, cradle rings, Vixen dovetail, retractable dew shield, padded case, and optional-mount configuration support portable visual astronomy and wide-field astrophotography.

The aluminum optical tube uses a focuser lock screw and includes the main hardware required for integration with a compatible mount, but a complete observing system still requires an appropriate diagonal, eyepiece, tripod, and support platform. The short focal length is suited to broad framing, while proper focusing, mount balance, dew control, dust protection, and secure case storage help maintain consistent field use.
