OVERVIEW
The APO140 ED is TEC’s first production model of apochromatic refractor and it is our “best seller”
telescope, since start in the end of 2002 about 600 telescopes have been sold.
Scope has number of features that in given combination are rarely found in one scope:
• Compact, lightweight tube assembly with retractable baffle and precision adjustable tube rings.
• Case for telescope has “carry-on” dimensions for most airlines (since these dimensions could
change, please double check weight/dimensional limitation prior to your flight).
•Telescope objective being “oiled triplet” by design transmits more light than any other type of
objectives; combination of “oiled \” design and modern coating that makes lenses almost invisible.
• Precision rotatable focuser with coarse and fine focusing, with 2”eyepiece holder.
• The focuser features a specially designed collet made of metal wich is insensitive to temperature
and holds loads with high precision when concentricity of focuser tube and axis of the eyepiece or
camera attained automatically by definition.
