07-16-24 Today, we introduced the 13035TCC-2 and 13035TCC-3 Tri-TCC Telecompressor Correctors to replace the QUADTCC-130. Please refer to the product links for more information. 

The following historical information is provided for your reference. 

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!

The new Quad TCC (four element Telecompressor Corrector) when coupled with the Astro-Physics 130 Starfire GTX is an imaging machine at f/4.5 and a focal length of 585 mm. It covers an approximate 3.5 x 2.4 degree field when using a full frame 35 mm sensor and an amazing 3.5 x 3.5 degrees when using a 16803 sensor! There will be no need to mosaic your images, but when you do…Wow! 

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 our new 3.5” focuser to provide coverage of a full frame sensor. 130GT owners can celebrate with the knowledge that their 2.7” focusers can be upgraded with the 3.5” focuser and then also use the Quad TCC.

The male threads are 3.270" x 16.

QUADTCC-AP130 Includes

  • QUADTCC housing with 4-element optical system
  • EXT327-22.1, 22.1mm Back-focus spacer
  • Two machined covers

Back-focus Spacing

  • Back-focus distance is 102.9mm - measured from the back flange of the TCC to the camera sensor.
  • Back-focus spacing with the 22.1mm back-focus spacer is 80.8 mm +/- 1.0 mm - measured from back flange of the spacer to the camera sensor. 

Use with CMOS Cameras up to 35mm

Adapters are available for use with CMOS cameras with thread sizes of 48, 54 and 68mm. These are designed for the popular CMOS cameras currently available that utilize the 55mm standard spacing. The EXT327-22.1 Back-focus Spacer is required for this image train. Refer to the 130GTX & 130GT with 3.5" Focuser CMOS & CCD System Diagram - Telecompressor Correctors.

  • ADA327-48, 3.27" to M48 Adapter (new July 2024)
  • ADA327-54, 3.27" to M54 Adapter (new July 2024)
  • ADA327-68, 3.27" to M68 Adapter (new July 2024)

Use with Canon EOS and Nikon 35mm DSLR and Mirrorless Cameras

We recommend using the 22.1mm Back-focus Spacer (EXT327-22.1), which will provide back-focus spacing of 80.8mm for coupling directly to our camera adapters below. Refer to the 130GTX DSLR & 130 GT with 3.5" Focuser and Mirrorless Camera System Diagram. 

  • Canon EOS DSLR Camera Adapter with large 1.875" (47.6mm) diameter stainless steel bayonet. (ADATCCEOS)
  • Nikon DSLR Camera Adapter with large 1.73" (44mm) diameter stainless steel bayonet. (ADATCCNIK)
  • Canon EOS Mirrorless Camera Adapter with large diameter stainless steel “RF” Lens bayonet. (ADACAN-RF)
  • Nikon Z Mirrorless Camera Adapter with large diameter stainless steel “Z” Lens bayonet. (ADANIK-Z)

Custom Adapters

If you need an adapter for a configuration that is not described above, we recommend that you contact PreciseParts. The Build-An-Adapter tool has the information that you need and is easy to use.

Optical Spacer Rings (Part #SRSET-327)

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.

You may wish to consider a set of three 1 mm thick spacer rings to adjust the back-focus spacing of the Telecompressor Corrector, as needed
