Description
Carbon-fiber portability and ED optics shape the Levenhuk AP 80/500 Ra R80 ED Carbon OTA, an apochromatic 80 mm refractor with a 500 mm focal length and listed f/6.25 optical ratio. Its ED doublet objective, fully multi-coated optics, carbon-fiber tube, 2-inch dual-speed Crayford focuser with 10:1 reduction, 360-degree rotation, low-profile mounting bracket, retractable dew shield, reducer adapter, and aluminum flight case support portable visual astronomy and astrophotography.
The standalone optical tube is intended for use with a separately selected mount and diagonal, while the carbon-fiber structure supports the supplied lightweight configuration. The 500 mm focal length provides broad framing for suitable targets, and the focuser lock, dew shield, case, and photo-thread mounting interface support setup, transport, storage, and camera-related integration when compatible equipment is used.
