The TEC 110 mm fluorite refractor provides a 616 mm focal length at f/5.6. Its oil-spaced fluorite triplet is intended for wide-field imaging and visual observing. The fluorite element is calcium fluoride, positioned between the two outer elements of the triplet.
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. The front lens has multilayer hydrophobic coatings.
Focusing
The supplied focusing arrangement is TEC dual-speed focuser; fine adjustment on both sides. TEC specifies 160mm 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 weight of 5.7kg and a retracted/transport length of 610mm. Accessory-loaded weights, where supplied, are shown separately in the technical table.
Current exact-model TEC page used; old ED or earlier-generation manuals are not substituted. Published metric dimensions are selected where imperial conversions disagree. Page footer incorrectly repeats APO140FL item metadata; the named APO110 description and 110/616 specification table determine the model.
