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

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.

If you have multiple scopes from the list above and wish to purchase a Backfocus Spacer separately in order to use the QuadTCC on the different scopes, below are the spacers listed by length (reference the table above) and corresponding part number.
Backfocus Spacer Length	Part Number
