Special Order

0.72x Quad Telecompressor Corrector for: 
** 130 StarFire GTX and EDFGT (with 3.5" Focuser) Refractors (QUADTCC-AP130)
** 140/160/180 Telescope Engineering Company Refractor (QUADTCC-TEC140/160/180)


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 male threads are 3.270" x 16

Backfocus Spacing

Scope Part Code Backfocus Spacer Spacing with Bf. S. Spacing without Bf. S.
AP 130 GTX QUADTCC-AP130 22.1 mm 80.8 mm 102.9 mm
TEC 140 QUADTCC-TEC140 18.3 mm 80.8 mm 99.1 mm
TEC 160 QUADTCC-TEC160 17.0 mm 80.8 mm 97.8 mm
TEC 180 QUADTCC-TEC180 16.0 mm 80.8 mm 96.8 mm


Important Note: When ordering the QuadTCC for a TEC scope you will also need to order a Drawtube Endcap (S35RFAA) for the focuser (see part listing below). This only applies to the TEC focusers. This part is integral to the Astro-Physics 3.5" focusers and is not needed as a separate purchase. The S35RFAA screws onto the drawtube's 4.100" x 24 thread (same as Starlight Instrument's 3.5" focuser endcap thread).


Optical Spacer Rings (Part #A5025SET)

In most imaging setups it will not be necessary to modify the spacing distance. However, there may be some sensor/camera combinations that can benefit by making slight changes to this spacing.

A set of three 1 mm thick spacer rings is being offered that can be used in special circumstances to modify the backfocus spacing of the Telecompressor Corrector.
