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!
Important Note: When purchasing the QuadTCC the proper length Backfocus Spacer is included for the scope specified. However, 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).
