Product Details

  • This is a 0.72x Quad Telecompressor Corrector for a 140 mm, 160 mm, or 180 mm Telescope Engineering Company (TEC) Refractor: (Select which refractor you have.) Expand your field! Reduce your f/value, speeding up the collection of photons, and do it with pin-point stars all the way to the corners of your full frame 35 mm sensor.

    Four carefully matched glass elements are carefully figured and then coated with the very latest multi-coatings to produce this optical wonder.  All mechanical parts, including the covers, are CNC machined and black anodized with a lustrous finish.

    The Quad TCC takes advantage of Astor-Physics' new 3.5” focuser to provide coverage of a full frame sensor.


    AP-QUADTCC_with backfocus spacer

    The QuadTCC is shown here with a scope Backfocus Spacer.

     The QuadTCC will work with Telescope Engineering Company's APO 140ED f/7 scope, making it a 700 mm, f/5 flat-field imaging scope! No fancy modifications are needed…simply attach our Drawtube Endcap (S35RFAA) to TEC's Starlight Instrument focuser, then slip in the QuadTCC and you're ready to go.

    The TEC 160 and TEC 180 scopes with the Starlight Instruments 3.5-inch focuser can also employ the QuadTCC (a different backfocus spacer will need to be used). 

    The backfocus spacing (as measured from the rear flange of the backfocus spacer) is 80.8 mm +/- 1.0 mm.

    The male threads are 3.270-inch x 16 tpi.
