TEC APO160 f/11 Yellow Submarine

TEC APO160 f/11 Yellow Submarine

The TEC 160 mm fluorite refractor provides a 1760 mm focal length at f/11. Its air-spaced fluorite doublet is intended for high-magnification visual and planetary observing. The fluorite element is calcium fluoride, positioned at the rear/inner position of the doublet.

Optical and mechanical construction

The objective uses a precision aluminium cell. An aluminium tube with internal anti-reflective treatment and baffles helps suppress stray light.

Focusing

The supplied focusing arrangement is Starlight Instruments Feather Touch FTF3545; rotating; 9:1 fine reduction; 2-inch collet. TEC specifies 250mm from the focuser reference to the focal plane; this telescope backfocus is distinct from the spacing of an optional reducer or flattener.

Dimensions and configuration

The manufacturer lists an OTA estimated weight of 28 lbs and a retracted/transport length of 1500mm. Accessory-loaded weights, where supplied, are shown separately in the technical table.

Compatibility notes

Current exact-model TEC page used; old ED or earlier-generation manuals are not substituted. Published metric dimensions are selected where imperial conversions disagree. Manufacturer TBD rear-wheel diameter and glass weight are omitted; OTA weight remains its published 28 lb estimate. Shipping-crate data is not treated as a telescope dimension.
